Laszlo | Runs | run entry - run063 | |
open file : run063
beam: 118Te52+
energy: 10 MeV/u
purpose: data with TARGET ON, we had to stop becasue Ulli was noticing some strange effects with the target density. He needs now time to optimize that.
Detector position (Si): -24 mm
run start at 15:04 , first file: run063_0001.lmd

Laszlo | | MCP can monitor target | |
now with the MCP we can see clearly the effect of the target :) (scintillation?)
so we want to scan through the target thickness with the beam and choose the best position afterwards.
We are making 3shoots for each bumb position (we change the bumb to make the intersection between beam and target) starting at ~14:
the data will be saved at the lxg1299 data.local2/hillenbrand/Laszlo folder |

Pierre-Michel | Detectors | Recoil detector | |
We turn on Recoil detector, to use it as a monitor for target overlap.
MCP front -2500 V for highest signal rate.
(Used to be -2250 V during previous beam time.)
DAQ triggered with 1 kHz clock in 2nd trigger input.
(2nd trigger used to be x-rays in previous beam time.)
The picture shows the increase of the Recoil rate when increasing the voltage from 2250 V to 2500 V in steps of 50 V. The last shot was taken without beam, so just target on. |

Laszlo | General | target optimization | |
previous position of the beam at target was -3mm (for the night position)
max. intensity position of the beam at target 1s -1mm. --> now it is set to this position
now Ulli also increasing the density of the jet. Right now Ulli is warming the noozle. --> takes 1hour roughly.
Earlier: 1.4E13

Jan | Runs | target incident | |
in run 66 or 67 we had a single ESR cycle for which the target didn't switch off for new injection and deceleration etc.
Very likely the DAQ also didn't get an OFF signal and collected OFF data to the TRIGGER=1 (ON data) branch.
As a consequence we collected about ~100 counts on the Si in one shot, which was about ~20 counts before this shot.
attached:
1.picture of the target density and beam current at this time. |
