Run Plan for beam test 2000

Here is a first draft of the run plan for the PrimEx beam test 2000.

Before beam is established in the Hall:

1. Take pedestal run

2. Take cosmic data until beam arrives

3. Make sure calorimeter is parked away from beam line while beam

   is being established in hall.

After beam is established in the Hall:

1. Ask MCC to restore position to previous Rad-Phi conditions (but with a beam current of 5nA).

2. Keep beam current at 5 nA and do a Harp scan.

3. Set beam to 50 pA (remind MCC to keep orbit locks OFF)

4. Move calorimeter into position using TAC GUI. (See logbook pages 19 and 11.)

5. Verify trigger timing (MOR*ST) using scope in control console

6. Check ADC gate timing using scope in control console.

7. Gain Match all crystals.

• Keep beam current at 50 pA (orbit locks OFF)

• Center beam on each crystal, adjusting voltage as needed by checking online histograms.

• Iterate until convergence (no more than 4 passes)

1. Center beam on central detector of calorimeter and take data for 30 minutes

2. As soon as you have an accurate estimate on the time for finishing with Pb-glass1, page Doug Tilles (849-7566) if he will be needed to crane in the PbWO4 calorimeter.

3. Also notify RadCon that you will need a survey of the calorimeter so that it can be worked on.

   Try and set up a time so that we minimize beam time lost.

4. Move calorimeter to each point indicated on chart and take data for about 2 minutes per point.

1. Remove Pb-glass1 calorimeter from Table. Move it to an out-of-the-way spot near the outside of the alcove.

2. Install PbWO4 calorimeter. (Make sure temperature control system is on and readout system is connected). If questions about the temperature readout system arise, contact Eric Clinton at 881-9671 Rm 244.

3. Repeat 1-10 above procedure for PbWO4 calorimeter. The PbW04 calorimeter has 4 different sections, each of which needs to be tested.

1. Remove Pb-WO4 calorimeter.

2. Remove bases and connector plate from Pb-glass1 and install in Pb-glass2.

3. Install Pb-glass2calorimeter on TAC table.

1. Repeat 1-10 above procedure for Pb-glass2 calorimeter.

• Arrange for RadCon to come survey the beamline components in the alcove including the calorimeter and collimator as well as any items we wish to remove from the hall at this time.
• Remove Pb-glass2 from TAC table
• Make sure all three calorimeters are moved out of the way of the Rad-Phi experiment in a storage position until we have a longer access time.
• Remove the collimator and place on the floor.
• Replace the Beam Profile Monitor (limit switch, support hardware,etc...)
• Un-do the changes to the photon trigger described on page 15 of logbook.
• Unplug ethernet cable to Temperature control PC on both end and coil back up in alcove.
