 		Maintainance
O Pekar,
T Hollander,
E Rood

Decide to revert back to original HVE CPU configuration
(Had tried arhus 2 x CPU system). Tank briefly depresurised for modifications
Mar 7-11
 Mar 7-11

 		Conditioning and
Beam Energy Calibration
Al(p,n)Si, 5.4MeV threshold
SH Connell,
T Hollander
O Pekar
Students
 4 - 7 MeV p
Conditioning now gives correct behaviour.
Can redo calibration more accurately.
HV also more stable under regulation.
Digital readbacks reset to new calibration
