Both clover detectors were moved. They are in a symmetrical position. The end on the clover nose is of the order
of 3-4 mm from the AIDA tunnel.
See sketch of CLOVERS with respect to beam.
See photos of the insertion distance of
both CLOVERS |

60Co source
Source ID: CD395
same type as 133Ba source
Start: 20:57
Stop:21:18
Position: z=0 cm, No AIDA
Pulser connected
There was an small file (dlt) before this run with no pulser connected (170525_2054_60Co_z0cm_004.dlt),
that run for only 3-4 min.
Files
170525_2057_60Co_z0cm_005.dlt
170525_2057_2118_60Co_z0cm_pulser.root
Comment: we noticed that the two clovers had different statistics for the 1332 peak. To be checked why
(source not in place ?)
The pulser shows similar counts, so the reason can not be deadtime
Answer: the D4 was not in its right position !!!!, efficiency calibrations have to be repeated :-( |

Thu May 25 12:49:55 2017, AT, JLT,PC,AA, Clover, 133Ba, LN2 filling

We started the measurement of the source when the N2 filling started. Just to check if there are funny things
related to the filling.
Start: 18:45
Stop: 20:48
The source was in position z=0 cmm (no AIDA)

Mon Nov 5 06:46:30 2018, KR, YR, MW, JLT, ..., Clover check
|
With detectors still on the floor we check signals and found
that D4 gives no signal with PA power. Two power supplies/cables were checked.
The detector was still working just before Jungclaus experiment. In July it was working.
Temperature monitors OK: 76-80 units
We mount both CLovers in position and make all connections.
We apply HV and check the resolution of G7.

is still pretty good

Sun Oct 22 05:15:26 2017, RG,RY,MS,ATD,JA,JLT, Check of YSO 12x
|
We start a systematic check of YSO in BRIKEN DACQ
WE check and correct a configuration file for YSO alone
Conf file: 171022_1306_YSO_Conf.xlsx
First measurement:
change the light pulser attenuation and check
changes of X and Y position
Root file: 171022_1314_pulserAtCenter.root
We change configuration file to remove amplitude
range condition to buil position
New configuration file:171022_1332_YSO_Conf.xlsx
Now start moving the light pulser position using a mask:
Light pulse position: Top Left Out
Root file: 171022_1335_pulseTopLeftOut.root
Light pulse position: Bottom Left Out
Root file: 171022_1341_pulseBottomLeftOut.root
Light pulse position: Bottom Right Out
Root file: 171022_1345_pulseBottomRightOut.root
Light pulse position: Top Right Out
Root file:171022_1350_pulseTopRightOut.root
Light pulse position: Top Left In
Root file: 171022_1401_pulseTopLetIn.root
Light pulse position: Bottom Left In
Root file: 171022_1406_pulseBottomLeftIn.root
Light pulse position: Bottom Right In
Root file: 171022_1410_pulseBottomRightIn.root
Light pulse position: Top Right In
Root file: 171022_1416_pulseTopRightIn.root
Now we ramp the PMT high voltage starting at 600V:
600V, 650V, 700V, 750V, 800V, 900V, 950V, 1000V, 1050V, 1100V, 1150V
Pulser at Top Left Out

Tue May 5 05:04:00 2015, J.L. Tain, J. Agramunt, G. Kiss, Change of degrader thickness
|
For EURICA measurements degrader thickness were increased
trying to decrease MACI and AIDA trigger rate
Before we had 5.7 mm of Al
Now we have:
Degrader: 4.0 + 1.0 + 0.6 + 0.4 +0.3 = 6.3 mm of Al
also 2x 0.8mm Al plates were added before
the MACI start detector (thus covering partially AIDA)
Trigger from AIDA will be taken from 3rd DSSSD |

Thu May 25 13:24:02 2017, AT,PC,KR,JLT,AA, CLOVER, detector not in its rigth position
|
We have noticed that D4 is not in its right position. That explains the different number of counts in the
detectors.
Probably of the order of 3 cm away from its nominal place.
The position of the other detector should be also checked.
Efficiency calibrations need to be repeated |

Source details:
Diameter: 25.05 mm
Dz: 3 mm
Source ID: CD 392
With pulser

Ps. See that the pulser generates peaks in the region 250-270 keV (to avoid people to invent new levels (and
gammas) populated
in the beta decay of 133Ba). |

Source in position z=0 with the carton (cardboard) high-end, high-tech holder, but no AIDA (of course).
No pulser. Remember that the pulser is providing peaks around

Clover calibration with 152Eu
Used peaks [keV]: 121.7817, 244.6975, 344.2785, 444.000, 778.9045, 867.378, 964.100, 1112.074, 1408.011
Up to 444keV is lower energy region, above 778.9045 is higher energy region.
All the peaks were fitted with Gaussian + Second Order Plolinomial(background) + Step Function(background).
Parameters: Second Order, First Order, Offset
