Some things weren't in the shift report - so I send them for completeness.

 The aim for this stack is to time the hodoscopes, to establish a charged 
 trigger and a neutral trigger, to measure rates, generate gates to allow
 timings, and to write tape to allow detector and software commissioning.


 E835 SHIFT REPORT: #1 16:00 to 24:00   9/10/96 .....addendum


 On shift (official): EM, SA.
 Present            : SB, RM, PM, SP, KG, MC, TP, ET AL...




 ANTIPROTON BEAM: (SP)
 Pbars were stacked from about midnight of 9/9 till 16:00. Problems with
 debuncher to accumulator kickers limited stack rate to about 0.4 ma/hr till
 mid morning when the rate went up to about 1.8 ma/hr. By 16:00 there were
 15.5 ma in the machine - plenty for our initial studies.
 The beam lifetime - target off - is only about 80 hrs; there is poor vacuum
 at both AP-50 and at A-30. The A-30 will have to be investigated, we assume
 the AP-50 vacuum will improve with time. As mentioned below, a vertical scan 
 was performed early in the shift and a plot is in the logbook.

 JET TARGET: (MM)

The jet is on from 5:38 p.m. with a density of 8 e12 atoms/cc.

The beam lifetime is 89h without the jet and 75h with this tiny jet.
The reason of the short lifetime, without the jet, is the vacuum
(3e-8 torr) in the jet target region and a leak near the BV307. This valve 
is about 1/4 of the antiproton length upstream the jet target. I remind
you that we started the jet target only Sunday evening. 

Using the beam, they did the vertical scan of the jet reading about 6.5
mm, within an error of about .5mm this is the same jet diameter we
measured at PAB

I left in the counting a table and a graph with the nozzle pressure and
temperature necessary to achieve the densities from 8e12 to 2.5e14
atoms/cc. An automatic procedure that will do this job entering the
desired density will be shortly ready.
