    keyword=Target Troubles

    Major target troubles for H2 on loop3 as follows:

    -Cell properties for loop3 seemed to still be set for D2. Had to change beam dE/dx from 2.6 to 4.8.

    -PID temperature control sensor seems to be set incorrectly and does not read out the same temperature as the cell temperature. Temperature difference is about 0.30 K.

    -PID beam compensation was initially turned off and the fan was set initially set to 0%. Has been corrected.

    -PID did not respond well to beam power and adjusted the HPH somewhat erratically. Seemed to work a little better after dE/dx was changed.

    -Target ladder screen still shows loop3 as D2-4cm and D2-15cm, when D2-15cm is really H2-10cm.

    Total experiment time lost while troubleshooting was approx 1 hour.
