This entry is a followup to: 30974
keyword=beam returns, table of resultsPermission was granted by the powers-that-be to
mask the ion chamber at the dump. We will proceed
to run at 30 microamps and up. The table below extends
the one at halog 30997.
Run..........Current...............T1 Rate..........Temp
1283..........30....................8500................179
(It is odd. T1 had been 6650 at 30 micro before the long wait.)
1284..........35....................10,200..............200 to 210
1285...........40...................11.6 kHz...........224 to 230
1286...........45....................12.5 kHz..........243 to 247
1287..........50.....................13.6 kHz...........257
Now we will leave it like this for about an hour to see how
stable it is. Results so far are plotted below. We will
repeat the low current points at end of test, time permitting.
