trim scans for Be beam 158 GeV |
|
|
The intensity of beam about 250k.
T2/T1 = 8% for target in
T2/T1 = 5% for target out
Last attachment is the test of the beam intensity for Be run to choose the best one.
Attachments 4,5 and 6 -> Target in:
High intensity (500k on S1), Taget in,
Medium intensity (300k on S1), Target in,
Low intesity (150k on S1), Target in,
Attachments 7,8 and 9 -> Target out:
Low intesity (150k on S1), Target out,
Tabel after scan of intesity:
