[Bonuslist] Next General BONuS Meeting

[Gabriel CHARLES]

Dear BONuS collaborators,

   Please find in this email the abstract I would like to submit for the 
April APS meeting. It will be in January in DC. Your comments are 
welcomed. The submission deadline is tomorrow, please accept my 
apologies for the late notice.

The idea is to give a very general introduction to experiments at JLab 
detecting low energy recoil particles
then to focus on the hardware for BONuS12 and ALERT. The first draft of 
the outline is here:

S1-S2-S3: recoil and JLab
S4: introduce the RTPC for BONuS
S5: new features of it
S6: ALERT
S7-S8: R&D

The corresponding abstract would be the following one:

Title: Low momentum recoil detectors in CLAS12 at Jefferson Lab

Part of the experimental program in Hall B of the Jefferson Lab is 
dedicated to studying nucleon structure using DIS on nuclei and 
detecting low-momentum recoil particles in coincidence with the 
scattered electron. For this purpose, specially designed central 
detectors are required in place of the inner tracker of CLAS12 to detect 
particles with momenta below 100 MeV/c. We will present the status of 
the BONuS12 RTPC detector that will take data within the next 2 years. 
We will detail the main improvements made from the previous BONuS RTPC. 
In a second part, we will discuss another recoil experiment, called 
ALERT, that has been proposed to run in Hall B. The constraints being 
different, the recoil detector is based on a drift chamber and an array 
of scintillators. We will present the main differences between the two 
detectors and summarize the R&D performed to develop the ALERT detector.

Best regards,
