Max was training me on the HV QE scan procedure and new spot move procedure.

Moved from (12750,19200) to (13400,18900), QE increased to .54 for Hall C, with other halls in similar ratios to what they were after the last spot move.

Found some improvements for procedure, successful test of procedure and system.

Before replacing the preamp, we cycled the harp using the preamp test signal. This produced a signal amplitude of 120mV, see fig. 1.

Replaced the preamp and used a test signal of 200mV (original test signal was 700mV), see fig. 2.

Cycled the harp using the modified preamp test signal, this produced a signal amplitude of 40mV. See figure 3.
