    Default 600 Watt Short Arc M-134 Cannon Light - INFANT AN/ASQ-132

    After 2 weeks of excitement and anticipation this up till now unknown military light has arrived. Iím extremely pleased and a little bummed at the same time. The seller could not tell me much about the light except that is was tested (according to the inspection tag) and in working condition. He could not tell me if it was incandescent or Short Arc. He offered to remove the infrared lens and snap a pic but that never happened before the end of the auction. So, I just took a chance and bought it knowing it could be simply an Incan. Without further adieu, I introduce the 6" Light Cannon:


    Short Arc de Triomphe. Arc chamber is 1.125" in diameter. I'm guessing it's a 300 Watt light but conceivably, it could be 500 Watts EDIT: It's 600 Watts




    Short Arc Powered by Eneloop




    All Business




    All More Business. The reflector is 5" in diameter




    Target In Sight, Sir




    Fan The Flames




    Cool it Dude




    Half Life



    Cover Your Eyes




    Cannonized




    Bottoms Up




    Locked But Not Loaded




    Now for the disappointing partÖThe ballast is not in the can! Big disappointment! EDIT: The ballast IS in the can!!! The reflector, bulb and its support system occupy the front half and the heat exchanger, input connector and cooling fan occupy the back half. Looks like I have my work cut out for me to find the ballast and power supply. But all-in-all, Iím still ecstatic in having the light.

    Although I have not pulled it completely apart yet, from what I can see from both ends, there appears to be no lamp electronics in the can. But I'm not 100% sure. In between the back of the bulb and its support mechanism, and the rear radiator, is another radiator in the bulb chamber. A metal bulkhead separates the two radiators. What has me wondering though, is why there is a 9-pin connector leading into the can. Besides the Cathode and Anode connections (the two large pins), there needs to be + and - leads for the fan and possibly a common ground between this light and whatever it mounts to and the power supply. So that's 5 leads. What are the other 4 for.

    Well I was 90% sure there was no ballast and ignitor in the can but to my amazement and sheer joy, its all there, built on the framework that holds everything together. There’s also another cooling fan inside the lamp chamber and it looks to be a closed cooling system. The inside fan recirculates air from the inside of the radiator throughout the lamp chamber, by the bulb and back to the radiator. The outside of the radiator is cooled by the fan in the back chamber.

    I sent pics of the lamp and light off to Advance Radiation Corp. (ARC) and they think based on the pics that there are some broken connections and that the bulb may not work. They say it's somewhere between a 500 Watt and 800 Watt lamp and that they can make me a replacement. So no issues there. If I can get this baby going, I'll have the "500 Watt Spectrolab Starburst" that I've always wanted but in a much more compact, handheld package! I'll be excited to find out how tight the beam is. By coincidence, ARC's founder, Ray, the gentleman I spent some quality time with in trying to get a bulb made for my communicator, had a bulb mfg business before he started ARC. The company name initials were PEK. Guess what's on the base of my bulb and who made it? ARC also believes this is/was a tank light.

    I’ve only given the circuits a cursory look but am still not quite sure why all the 9 wire connections are needed. There are 2 small pin grounds to the case. There are the main connections for the Cathode and Anode lamp bases (large pins) and one small pin positive for the fans. The other 4 small wires are going to components on various places on the boards, one being a small blue wire to the transformer. I’m hoping some of you might be able to suggest the purpose of them and what I should feed them with, if anything. I'll come back later with some pics showing where all the wires go.

    One of 3 magnets affixed to the reflector. Two small and one larger. Purpose is to straighten out the arc. The larger the Wattage and gap, the more tendency for the arc to bow.

    Thanks to Phil Ament, I know know the application of my light. It's an Infrared 500 Watt, M-134 Gatling gun mounted light used on Huey helicopters in Viet Nam in conjunction with the INFANT1 System. Here's a link to a pic. Look just below the horizontal stabilizer at the round tube sitting on top of the cannon.

    //cs.finescale.com/FSMCS/forums/p/90402/883686.aspx

    An excerpt describing the system: The Iraquois Night Fighter and Night Tracker (INFANT) (AN/ASQ-132) system was equipped with Low Light Level Television (LLLTV) eqipment to find targets at night (2 8 inch screens up front and a 14 inch screen in the cabin). The right sensor formed electronically intensified images and displayed them on a TV monitor. The left sensor housed the LLLTV. All the INFANT hueys were armed with eth M21 weapon system (M134 Minigun+M158 7 shot rocket pods). a 500 watt Xenon searchlight was on top of each mini. "Dim tracer" ammo invisible to the naked eye was developed especialy for the INFANT system. The system was developed by Hughs aircraft in 1967. It went to Vietnam with the 1st Cav in 1969.

    Can someone knowledgeable in electronics ID the two (one larger and one smaller) somewhat rounded diamond shaped components just below the black transformer?

    I believe they are both power transistors.

    The small one is a Motorola 2N3767 (TO-66) power transistor. A little digging reveals that it's likely rated at 4A, 20W. The bigger one is more worn, but seems to be a Motorola MJ413 (TO-3) power transistor, rated at 10A, 125W.

    Would more specific pics help? A pic of where each of the 9 wires lands?

    I know 3 already. The Anode and Cathode connections - the biggest pins/wires and separate power for the fans. 3 down-6 to go. Two pins went to frame ground at least in testing with the continuity mode of my meter. But one of those seems to go to ground thru a tiny component. So maybe it's 4 down and 5 to go. Nowhere in the light does it indicate that it's a 28 Volt system so I am making that assumption, too. I've got a huge TM manual on the entire INFANT system coming that has some pages dedicated to the light. It's mostly electrical schematics in the manual. I asked the person before I bought it if he could look at the searchlight pages for me to see if he could make anything out regarding the 9 connection wires which he did but he is not electrically inclined and he does not see any type of pic of a 9-pin input so I'll just have to wait till it arrives.

    well the schematic would be the most helpful, that would give your the exacts of whats what, however, it may not give voltage ratings. does it have a focus mech? if so, i'd gather 2 of those pins are for spot/flood. they COULD conceivably be for a "strobe" function however i find that unlikely on a huey target lighting system, perhaps a "standby" circuit? closer pix may help, however, tracing electronics is alot easier with hands on view. if you have any issues reading the schematic, i'd be more then happy to take a look at it for ya!


    edit: upon closer look, id say that atleast ONE of, if not 2 pins are "trigger" pins used to "strike" the light upon start up, much like some of the larger home made XSA systems, where constant power is applied to the bulb while lamp is "on" but it won't fire until actually lit 1st. then to shut off, all power is killed.

    No, no focus/bulb movement. I'll know more when I get the pages. Interesting the fan is marked 19V.

    Curiosity is getting the best of me. Why do some discharge tubes like flashtubes have that wire that wraps around it or goes end to end?

    Also, what is the part labeled S1 here, a solenoid, or a switch?
    http://i3.photobucket.com/albums/y79/BVH/PCboard.jpg

    Also, what's the big green box? Look like a big cap?

    All the connections look good to me, and all the parts look to be in good condition. Maybe one of those transistors shorted itself or something.

    Good question on what that part is. One of the 9 connection wires lands on it. It's very thin so I don't think anything moves inside it. The big green box is the igniter. I have no reason to suspect that any ballast parts are bad. ARC thought by looking at the pics of the bulb that it might have lost it's seal. But they can't definitely tell nor dedicate time and help to me until the beginning of June.

    EDIT Add. I should mention that the OEM connection cable that came with it is, of course, is 9 pin on the light end but it's a 15 pin on the other end. I haven't rung out the cable yet so maybe a bunch are not used or some are connected together at the 9-pin end.

    the large green box Could be the spark gap.... i've seen them that size, but only on larger systems.... usualy designed for 5kW pulsed CO2 Lasers.... BUT being this is a Mill Spec device, over compensation is NOT uncommon. maybe disconnect it and test witn DMM? if it's open, i'd say 85% thats what it is... (without looking right at it and following the wires thru the device) but it does look like it connects to that smaller white cap mounted near it.



    Side Note: was watching some old Voyager episodes and the name "500w Photonic Cannon" pop'd into my head for this lil gem of yours.

    that is the "trigger" wire... it's used when the HV starting surge kicks. on flash tubes, a Flyback xformer is the source of the HV pulse and unlike the auto HIDs, it only causes a "static" charge, which travels through that wire and ionizing the xenon causing the main charge from the "low" voltage high current cap to discharge across the tube. on XSA lamps, i'd guess it's just an added measure to insure the trigger spark gets the lamp started using less voltage then would normally be needed to initially jump the gap by ionizing right through the quartz itself.

    There is also another "trigger wire'ish" half loop of wire that comes up from the reflector housing directly underneath the stem on the bulb, half loops around only the bottom half of the stem and goes back down to the reflector housing. I've never seen this before. It does not offer any type of support so it's not structural. Any ideas?

    thats a ground wire. reduces static charge around the envelope and may reduce some (tho not alot) of the ozone. i've seen these on some high voltage glass discharge tubes of various types. helps lessen degradation of the tube and eliminates the static build up between bulb and chassis. (usually only found in systems with high potential in a confined package. i've had some gas lasers with those in them)

    Should it be touching the bulb or just close to it when I go to re-assemble? I can't remember how close it is to the trigger wire right now.

    well, having never seen one on a XSA persay, i'd have to say NOT touching the trigger wire for sure, and bulb contact.... well i'd say assemble it and see how close it is to the envelope,... if its looks like it's going to touch no matter what, i'd have to say it's sapposed to, if it looks like it's close but can go eather way, i'd say play it safe and keep it off.

    Yes, I guessed it should definitely not touch the trigger wire. I assume it would instantly melt.

    and possibly fry the starter circuit as well

    OK, the mystery is getting easier by process of elimination. First, only 8 of the 9 pins are used. #3 is not used. Also, wires #6 and #7 are directly connected thru this "sensor" (see pics) and go nowhere else - wire from Pin 6 comes from the connector, lands on one of the sensors' terminals and wire #7 is connected to the sensors' other terminal and goes directly back out to pin #7. The sensor is not connected to anything else by wires. It does, however ride on the frame but I don't know if this is just the way it's mounted or if it is actually grounded. So I'm guessing this is to trigger something else in the INFANT system and not used to run the light. Maybe an overheat condition sensor? So....3 Pins out of 9 could possible be defined now. One for the Anode and one for the Cathode. 5 out of 9. One black wire Pin for frame ground. 6 out of 9. Somethings got to power the transformer - light blue (thicker) wire, so there's another Pin - 7 out of 9. One pin to the cooling fans - 8 out of 9. So what is the purpose of the small Lime green wire that's going to the power transistor? Here's a diagram of the 9 Pin connections.
