Laser Target Designator / Ranger DESCRIPTION:
@j/MS-1Bh M The Loral Aeronutronic Model-11+ is used for laser target range and designation. This device is attached to the Loral Acronutronic F/A-18 forward looking infrared (FLIR) Pod located i
on the outer surface of the left engine inlet on the U.S. Navy F/A-18 aircraft.
The device is contained in an environmental controlled cavity (AN/AAS-38A FLIR Pod).
The device shown in Figure Nos. 1 and 2, contains two NRC-approved americium-241 (Am-241) sources j
(NR-136-S-
-g), for the removal of static charge, one at each end of the s&'s Q-Switch crystal permitting it to maintain its large characteristic discrimination ratio. The two sources are screwed and secured into the Optical Access Cover which is located on the laser transreceiver directly over the optics. The cover is an aircraft standard aluminum alloy machining, 7.5 inches long by 3.4 inches wide by 0.4 inches high, which mounts the sources. The optical elements of the laser are mounted within a sealed cavity directly below the cover. The cavity is approximately 1.7 inches deep and is also machined from aluminum. The sources are shown attached to the cover in Figure No. 5. The minimum thickness of the cover is.040 inches. The sources are placed approximately 1.5 inches apart and are threaded into the cover. An 0-ring is placed between the chassis and cover. The cover is secured with seventeenJ crews and is 17$
opened only for depot maintenance. This prevents the ingress of moisture and the cavity is filled with dry nitrogen. Once assembled there is no morral' access to the AM-241 sealed sources.
The AM-241 foil disk is crimped within a cylindrical stainless eteel (304) housing. This sealed source is then placed in an aluminum holder and then secured within an aluminum threaded
~P cylinder which is appropriately marked.
LABELING:
Each source assembly will be labeled on the sides of the threaded holder with the following: serial number, isotope, activity and the trefoil radiation symbol. The Optical Access Cover will be labeled as chown in Figurcc "O. 3 and A M 4CIc8tMNCE Wrm 10 CFR 204o%

DEVICE TYPE:
Laser Target Designator / Ranger CONDITI0llS OF NORMAL USE:
The sealed sources have obtained an ANSI classification of C54545. The device is subjected to a military aircraft environment and is expected to have a service life of 15 years. The extremes of environment for which the device is designed to withstand are as follows: temperature -62*C to 95'C; vibrations 50-2000 Hertz; high humidity; salt fog; explosion; sand, dust, and fungus. Due to the sealed construction of both the Optical Module and the FLIR Pod, the device shculo not be affected by atmospheric conditions.
PROTOTYPE TESTING:
The manufacturer reports that the device was tested to MIL-specs except for l
salt, fog, and dust. The FLIR pod that has also been tested to meet military specifications (111L-STD-810C). The device has been field tested in the configuration and with no incident of source failure.
_XTERNAL RADIATION LEVELS:
E The manufacturer reports that there are no detectable radiati7n levels above background from the device.

Th by er-ar+4 fa+=raati-s':
Ferrer,t Internat4ene+ has supplied an adequcte J. Qf" @y assurance and control program that conforms to MIL-Q-9858A.2M ".TO qualit A copy of the quality requirements governing the supply of the i
sources is on file with the Material Licensing Branch.
A Certificate of Conformity ensuring that the device meets the design specifications is supplied with each source and further checked by the USA manufacturer. The USA manufacturer evaluates each component of the module to conform with MIL-specs.

SAFETY ANALYSIS
SUMMARY
AN /P: prs '58 A WA Based cn our review of the information and design of the devic, the past history of the sealed source design, we conclude that Ncdel oevice is acceptable for custom licer. sing purposes.
Furthermore, we conc ude that this device would be expected to maintain its containment for normal conditions of use which might occur during the uses specified in this registration sheet.
