Subject: Baking tent removed, VI tests 

Baking tent, frame and trays fully removed from CARME chamber. Removal of baking frame required removing air lines from upper gate valve and repositioning of vacuum hose connecting turbo pump to backing line and turbo power cable. Some difficulty encountered removing upper baking frame now the target support frame is assembled. Small modification seperating section in two would aid future installation and disammebly. 

Baking trays removed with difficulty. Main baking tray bent to extract from the frame -> updated design required for future bakeout cycle. 

VI tests performed on the upper and lower detectors. Upper detector shows characteristic curve (attached plot), lower detector shows no response to increased voltage. Multimeter used on adapter boards with resistance of ~18.5 kΩ observed between bias pins for the upper detector. Open line seen between bias pins on the lower detector, some connections observed for other pins on the board -> requires further investigation.  

NOTE - Channel 0 on bias supply is unstable, should not be used. 

 Most equipment for installation of FEE's and coolant manifolds found, assembley of FEE holders started. Full list of current swagelock inventory as follows:
