Hall B Update

I walked over to the counting house to talk to the folks over there. They are cautiously optimistic about the most recent harp scans. Currently they are waiting for the target expert to arrive before they move to testing beam on the actual target. Right now, we in the control room are waiting with bated breath.

Scan of harp_2H00A

1 day 1 hour ago
Log Number: 4500043Logbook(s): Body: 

After some check we conclude that the tails at the 2H00 positions sre real and not artefacts coming from downstream.
The sigma of the X an Y areless tha 0.1 mm which is very nice.
The X profile on the bottom including tail is about 1.5 mm. Outside of this window we see single counts. Pick maximum is 200 kHz.
This will go throuhg the 2 mm hole of the target.
Y profile has a longer tail. Looking on the bottom (single counts) the beam spot spans 3 mm. The tail will not pass 2 mm hole.
The rate in the tail outside of the 1.5 mm is under 100 counts. Compare with 24 kHz in peak.
