Hi Mark,

Just to keep you informed, we're getting ready to assemble a new Hall B RICH detector in EEL 124. We've already started getting the safety documentation together and Marc McMullen has already been in contact with you about the lift and rigging portions of that.

We already know that we need to update a few lift calculations since for this assembly, we'll be using the stiffening tool on the detector during rotation.

The RICH collaborators are tentatively scheduled to arrive at the lab and be able to start working on January 17, 2022. On that day, we'll be able to review the rotation lift calculations and provide the final documents for the rotation lift plan.

After we provide the documents, what would be needed to have the lift plan approved? Hopefully the lift plan approval can be completed within a day or two so it doesn't interfere with the collaborator's tight schedule at JLab.

Thanks,

Tyler
