CHAPTER iti, SECTION 7 per month (including the reproduction work a cryptographic system was issued for the Con- RECORDS CENTER enabled requested by the Honolulu Office). The AEC Records Program was immaugurated in Mav. 1952 on a part-time basis. By 1 July 1953, 46 records schedules had been for- warded to the Santa Fe Operations Office for approval; 415 cubie feet of records were forwarded to less expensive storage faclities: 220 cubic feet of records were transferred to the AEC Reeords Service Center at Los Alamos. New Mexico: and 149 cub’c feet of record. were destroved. A full-time Records Officer was appointed on J July 1953, at which time the H&N Records Center started operating on a full-time basis. By the end of 1953. the Records Center holdings totaled a6t cubic feet. or double the amount months. reported for the preceding six Reference services furnished trom Records Center to the Home Office amounted to o3 in 1942. and 1.086 in 1953. The monthly average of reference services from 1 July 1953 to the end of the vear was 166. In 1954, a peak of 994 was reached during the month of April. then eraduallv decreased to 161 in June 1954. Investigations and ~<tudies regarding the passibihty of microtilming all vital records were made. However. the space-saving advantage gained through the use of micrefilm did not warrant the over-all cost of this undertaking in view of the fact that storage of vital records, by contractual agreement, necd not exceed seven Vears. COMMUNICATIONS TELEPHONE. On 24 July 1953, the 120-position PBN in the Home Office was replaced with a 160-position board. Approximately 45S. long distarce calls a month were made over a sevenreonth period. including the peak period. and soe ne te CONTA ea aa guyty cere 1. lat Gee atl. CaS wae.

Teletype communications between the Home Office and Emwetok were cffected by means of the radio teletype facilities installed at the AEC Communications Center at Los Alamos and fniwetok. All classified and unclassificd messages were sent over this means by TWX to Los Alamos, thence over the radio teletype circuit: direct) to Eniwetok. Incoming teletypes were relaved by this same means to Los Alamos. and then im turn relaved un ty Holmes & Narver, Los Angeles. by TWX collect. During Operation IVY, classified message s to Eniwetok were encoded in the Contractor s Home Office. then transmitted te Los Alame-~. Los Alamos decoded and re-encoded the me sages for relay to the Task Group Communications Center at Enwetok Atoll. In October 1952, prior to the commencement of CASTLI . tractors use in Los Angeles, and for the Communications Center at Eniwetok. This system H&N to send and receive messages classitied Restricted, Contidential, and Secret without the delay involved in having Los Alamos decode and re-encode these messages. “Back-up” communication circuits were available in the event of failure of the radio teletype circuit. The “back-up” circuit operated from Los Alamos to the AEC Communications Center, Sandia: from there messages were sent over Military circuits to Fort Sam Houston, Texas, thence through the Sixth Army Headquarters at San Francisco. From San Francisco, Messages were scat by Military radio teletype to the Communications Center at Oahu and from there to Eniwetok, In July 1953. due to continued adverse at- mospheric conditions resulting in the failure of the radio teletype circuit between Los Alamos and Eniwetok, Holmes & Narver was advised to file unclassified messages with the Army Conmunications Center in Los Angeles. These messages were then rclaved to the Sixth Army Headquarters Communications Center, San Francisco, where they were sent by Military radio teletvpe to Oahu, and thence to Eniwetok and or to HEN’s office in Honolulu. In March 1953, the Holmes & Narver Message Center in the Home Office was officially recognized by the Military as a “trained TWK tributary station of the Las Angeles Communications Center.” As a result of this recognition, H&N was furnished Military Procedure Publications which enahled the Message Center to operate efficiently and in accord with other units of the circuit.

This equipment was. until that date the type of equipment installed at the Home Office. The filing of classified messages continued through Los Alamos. However, after 5 April 1954 new equipment, formally known as an AKAN circuit, was installed at the Holmes & Narver Home Office, and encoded messages were permitted via a leased line to the Army Communications Center in Los Angeles. To expedite procurement. teletvoe facilities were also emploved between the Contractor and commercial companies within the United States. The peak in H&N’s teletype traffic was estabE shed during the months of August and September.
