Plan for FPP commissioning with unpolarized beam
-
Measure the carbon scattering efficiency for Tp
= 0.799 for carbon thickness of 22.9 (9''), 30.5 cm (3''+9'' doors), 41.9
cm (1 1/2''+6''+9''). Estimated time for measurement is 1.5 hours. Magnet
and angle change is hour. See fpp_scat_1
in following pages for details.
-
Measure the carbon scattering efficiency for Tp
= 0.586 for carbon thickness of 22.9 (9''), 30.5 cm (3''+9'' doors), 41.9
cm (1 1/2''+6''+9''). Estimated time for measurement is 1.5 hours. Magnet
and angle change is hour. See fpp_scat_2
in following pages for details.
-
Measure d(e,ep) quasi-elastic scattering at kinematics for
elastic ep at Q2 = 1.1 GeV2 (Tp = 0.586).
Want to measure instrumental asymmetries to 0.0015 level. Estimated time
for measurement is 2.0 hours. See fpp_scat_3
in following pages for details.
-
Remove carbon doors to do alignment of FPP chambers with
straight through tracks. Use d(e,ep) quasi-elastic scattering at kinematics
for elastic ep at Q2 = 1.1 GeV2 (Tp =
0.586) with hadron Q3 defocussed. Estimated time for measurement is 1/2
hour. See fpp_scat_4 in following pages for
details.
-
Measure the carbon scattering efficiency for Tp
= 1.012 for carbon thickness of 22.9 (9''), 30.5 cm (3''+9'' doors), 41.9
cm (1 1/2''+6''+9''), and 49.5cm ( all doors). Estimated time for measurement
is 2.0 hours. Magnet and angle change is hour. See fpp_scat_5
in following pages for details.

Measure the carbon scattering efficiency for Tp
= 1.332 for carbon thickness of 22.9 (9''), 30.5 cm (3''+9'' doors), 41.9
cm (1 1/2''+6''+9''), and 49.5cm ( all doors). Estimated time for measurement
is 2.0 hours. Magnet and angle change is hour. See fpp_scat_6
in following pages for details.
