The meeting came to order at 3:05 pm.
SEPTUM MAGNET
Septum magnet mapping is complete, so far as what was planned for CE78. Rinckel presented a written summary of the magnet's operating characteristics, and the measured field in the shielded channel for the Cooler beam. This shielding must clearly be extended as far upstream as possible. He would have liked to map the same region without the shield, for purposes of a potential publication, but one of the power supplies failed and could not be fixed before the Cooler closed for the current run. We believe Georg Berg is working on the analysis of the field data to revise and finalize the magnetic channel configuration.
PREPARATION for CHANNEL TEST RUN
The rest of this meeting focussed on Tom's week-by-week analysis of what needs to be done (and by whom) for us to be ready for beam on May 8. An updated version of his list has already been transmitted to the full mailing list. There were many comments and additions made. The scintillators are going to be close, but there did not appear to be anything impossible on the list. We will obviously need a lot of help from everyone to make sure we don't fall behind or forget anything in this critical 3.5 week period of access starting April 11.
Before that date we need to prepare as much as possible. In particular we need (Pancella) to devise an alignment strategy and make up or find any needed fixtures for that job. Of course we need to know where the magnets have to be. We also need a fixture of some sort to test the large vacuum window at the end of the channel, and to locate the Kapton it will be made from.
The meeting adjourned at about 4:06 pm.
