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. 
After a review of the physics motivation 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.
