Week of Oct-4-1999

To all,

1. The water line has been re-soldered with a new copper connector. And
it has been leak checked by both uday and me.
2. The damaged I/V channel has been changed. One other channel had bad
drift, and its DC offset has been re-adjusted.
3. The angle of the analyzer anode plate has been adjusted to 11 degrees
from 14 derees.
4. All 4kV treks fuses have been checked, replaced and modified if
necessary.
5. Fixed some problems of the H.V. controller. Change its power supply,
and some I.C. chips.
6. The bad rough pump is under repairing in the instrument shop.

We'll connect the I/V cooler tonight, and run primary beam if possible.
