In the first attachment data taken last night (field on)
In the second, data taken 2 days ago, field off.
So, data of last night is soo bad we should not make strict conclusion.
*Shift people should accurately monitor (run by run) the blast ps
current.*
* Also, shift people are expected to analyze a little more, so as to
notice,fi., that there was no left sector data for tofs 0-7*
While waiting for beam, last night the PS did trip (and apparently only
I noticed and informed ccr). The field off rates are consistent with this
summer. For field on, the background is terrbily high. The polarity
switch is not a software thing and is out of the discussion.
I bet my coke can that blast tripped and beam went astray.
