[Poltarg12] [EXTERNAL] Last minute APS abstract feedback request

[VICTORIA LAGERQUIST]

Hello all,

Pushpa and I will be submitting abstracts for the October DNP meeting and
welcome any feedback from the group (see below). The deadline is in a
little over a day, however. We apologize for the late notice!

Thanks!
Victoria


First Talk:

Design of a Longitudinally Polarized Target for CLAS12
The upcoming Run Group C experiments in Hall B of Jefferson Lab will
utilize the CLAS12 detector system and a new dynamically polarized target
of irradiated NH3 and ND3 to study the nucleon spin structure. The
dimensional constraints necessary for incorporation of this new target into
the CLAS12 detector system, as well as utilization of its 5T central
solenoid field, introduce unique design challenges. I will present an
overview of our solutions to these challenges including: precision magnetic
field optimization, and an innovative, rapid material transport mechanism
inside the target cryostat.


Second Talk:

 First Tests of the New Longitudinally Polarized Target for CLAS12

The Run Group C suite of experiments will measure multiple spin-dependent
observables by scattering the energy-upgraded 11 GeV electron beam from
longitudinally polarized nucleon targets inside the CLAS12 spectrometer in
Hall B at Jefferson Lab. The dynamically polarized target built for these
experiments has been extensively tested in the JLab Target Lab using an
auxiliary 5 T magnet. We will report on the operational experience with the
target, and the benchmarks achieved so far using various polarizable
materials with the complete target setup. Our results show that all target
components work well and that the project is on track for the scheduled
experiment that will run during most of the year 2022.
