SBS components

There are a number of hot topics in each component:

48D48 – many aspects of the design need key input from MC before production drawings can be produced

GEM chambers – prototyping, module quality, production yieldGEM electronics – performance: level of the noise, readout speed

HCAL – from the ideas, components, to a prototype and construction

ECAL – not the BigCal, active searching stage

DAQ - development, construction, 18 FastBus crate farm

He-3 – target conceptual design, Au is too soft for hot Rb atom

SBS collaboration

There is a need for an Experiment Coordination Committee

1) Each experiment accepted to be the SBS collaboration experiment will be presented at the ECC meetings and share the load of work

2) ECC should include a Hall A leader and one representative from each experiment selected by the experiment spokespeople 3) The goal of ECG is to expedite the SBS program and coordinate all efforts in development, running and publication plans/results of SBS.

SBS second group of experiments

There are several exciting suggestions post FFs:

SIDIS – talk by A. Puckett (experiment was approved in 2010)

PionSF(s) – see talk by T. Keppel at SBS meeting, 3/13/13

DDVCS (muons) – talk by A. Camsonne
