    0:30 MCC has finished its tuning operations and is able now to deliver up to
    50 uA. To deliver more current it needs however three hours' access to fix
    BCM power supply.

    0:40 Controlled Access in Hall A.

    2:15 Hall A status is now Power Permit.

    2:20 Hall A status has been restored to Beam Permit.

    2:30 100 uA delivered for testing purposes in Hall A; target empty.

    2:55 Beam ready. Raster 4x3; Fast Feedback on ; OTR IN and source Hall A set.
    Current intensity set to 5 uA. Arc tuning ACHRO.
    HARP Scan starts.

    3:05 Raster off; Target empty; HARP scan.

    3:10 OTR IN and source Hall A set again.

    3:15 : Target moved in; raster on; 10 uA of current intensity to chek spot size.

    3:25 spot size ont the screen about 4x3. We asked for a 25% increase of the spot size.

    3:27 The (uncalibrated) spot size on the screen is now : 5x4.

    3:30 Current intensity set to 5uA. New Harp Scan with Raster on.

    3:35 3HE Target commisioning runs start:

    1304: 5uA lost beam; fan 20%; PS: 5,1.
    1305: junk.
    1306: 5 uA; fan 20%; PS: 5,1; beam absent for a while.
    1307: 5 uA; fan20%; PS: 5,1.
    1308: junk.
    1309: 2 uA; fan 20%; PS : 2,1.
    1310: 1 uA ; fan 20%; PS: 1,1; NO FAST FEEDBACK ! (beam position stable).
    1311: 10 uA; fan 20%; PS: 10,1; FAST FFEDBACK ON again.
    1312: 20 uA; fan 20%; PS: 20, 2.
    1313: 30 uA ; fan 20%; PS: 30,3.
    1314: junk.
    1315: 40 uA; fan 20%; PS: 40,4.

    1319: 60 uA; fan 20%; PS:60,6.
    1320: 70 uA; fan 20%; PS: 70,7.

    6:45 current intensity was not further increased because of the heater power limit.

    1321: 70 uA; fan 24%; PS: 70,7.
    1322: 30 uA; fan 24%; PS: 30,3.
    1323: 1uA; fan 24%; PS: 1,1.

    7:45 Carbon target moved in to perform Nilanga's test on the optic of HRS. We asked for 5 uA.

    8:00 Because of the low rates, the current intensity was se to 50 uA. PS: 30, 1, 10 1;
    no slieve slits, no raster.

    1324-1326 junk.

    1327. Nilanga's test run. 50 uA. PS: 30, 1, 10 1; no slieve slits, no raster
