[Sneap] Unattended operation of accelerators [SEC=UNCLASSIFIED]

[Stephen C. Menasian]

David:

While I was at Lucent Technologies Microelectronics, it was standard
practice to run overnight if the RBS sample queue was long and there was
an urgent need for results. We had a 1.7 MV General Ionex Tandetron with
an automated data acquisition/sample changing system. I could load up to
24 samples for an overnight run. The probability of completing all 24
samples without problems was around 75%. The most common problem was beam
drift resulting in low or no current at the end of the run.

Radiation has never been a problem for this machine under normal
conditions (2.12 MeV He++) and the area monitors would shut the machine
down if excess radiation was detected. Access to the machine was well
controlled; so, there were no other safety issues.
