* Perform harp scans using 2H02 harp. Optimize halo counter voltages as needed.
* Once established, commission the chicane magnet, including a study of noise rates (halo counters + ecal) vs B field. (We may need to run slightly lower than nominal B for our given beam energy to afford adequate clearance to the 3 inch beam pipe connected to the new target assembly.The beam pipe must accommodate both straight through and Frascati bent beams.)
