Alpha data used: /May19/{R1,R2,R7,R8,R9,R11} (c. 380 hr.)
Absolute calibration calculated with relative calibrated data
Data then resorted with absolute and relative gains applied
Attachment 1 -> Ey vs Ex plot for all detectors, with slope Ey=Ex show in red. Some non-linearity present, but to first order looks good
Attachment 2 -> Alpha peaks pre- absolute calibration in DSSD0
Ex in blue, Ey in red
To determine absolute calibration coefficients, assigned leading edge of higher energy peak an energy of 7.4 MeV (Uranium decay series)
Divide this by the observed channel number (in keV) to get the absolute gain coefficients in keV/ch for Ex and Ey in each detector.
(Note, data already offset corrected, pulser walkthrough)
Values typically ~0.72 keV/ch
Multiply appropriately by relative gains obtained from gainMatch.cpp to get final gain coefficients.

Thu Jan 22 13:50:33 2015, Alfredo and Tom, Further measurements with filtered PSU
|
Jan 20, 2015
Test settings: DSSD biased at 100V, with 3.5 uA leakage current. Pulser at 0.5 V, split and inverted for both
positive and negative polarity. Frequency at 100 Hz.
++SHAPING TIME++
We varied shaping time (Tsh), and adjusted hold time (Th) accordingly. We measured the width of pulser spectra
for two channels using 'integrate' function of spectrum browser.
Tsh Th nnaida#11-2.6L nnaida#13-2.6L
[usec] [usec] FWHM [ch] FWHM [ch]
0.5 2 146 109
1 2 133 113
2 2 131 116
4 6 130 126
8 8 145 136
note: Tsh= ( 0.5*offset9 + 0.5) usec, Th= 2*offset7 usec
The first two data points where saved to file R44_0.gz, and R45_0.gz. Starting from the Tsh=2usec measurement,
NNAIDA#12 was causing communication issues with the merger/tape server, so we don't have files for last few.
Due to limited storange in AIDA PC, data was stored to external drive provided by Vic
(/media/data/TapeData/Test100/), and backued up temporarly also in Edinburhg
(/Disk/ds-sopa-personal/aestrade/data/AIDA/).
++THRESHOLDS++
Next step was to adjust threshold of the slow comparator, in order to lower them and take data looking for
background alpha radioactivity.
At this point NNAIDA#13 had stopped producing data (probably similar issue as NNAIDA#12, which could be
recovered with power cycling FEEs), so we used nnaida#14
FEE Eth rate/channel integral(pulse peak):integral(noise peak)
nnaida#11 0x40 115 Hz (~only pulser)
nnaida#14 0x40 115 Hz(~only pulser)
nnaida#14 0x20 ~350 Hz 2:1
nnaida#11 0x10 ~150 Hz 1:2 (one channel very noisy @ 15kHz)
nnaida#14 0x10 ~5 kHz (asic 1-3) 80:1
0x10 ~3kHz-100 Hz (asic 4)
For background run (see next elog entry) threshold values set at:
nnaida#11= 0x16
nnaida#12= 0x40
nnaida#13= 0x20
nnaida#14= 0x16 |
|
Thu Jan 22 14:26:10 2015, Alfredo and Tom, [DATA] R49: alpha background radioactivity
|
Jan20-21, 2015
R49_* are a set of files corresponding to an overnight background measurement, with goal of detecting alphas
from uranium decay chain contaminants.
The settings of ASICs are attached as a screenshot. The low comparator thresholds are (see previous entry):
nnaida#11= 0x16
nnaida#12= 0x40
nnaida#13= 0x20
nnaida#14= 0x16
For a significant fraction of the measurement, NNAIDA12 and NNAIDA13 were not generating good data. We
didn't
invest much time in solving the issue, as it's recurrent problem with NNAIDA12, but it seems some ASICS went
back to normal behavior overnight.
Due to limited storage space, data in external drive (/media/data/TapeData/Test100/), and backued up
temporarly
in Edinburhg (/Disk/ds-sopa-personal/aestrade/data/AIDA/).
A pulser walkthrough for this setting is available in runs R61-R65 (see next elog entry).
++ DATA ANALYSIS ++
A fraction of the runs (R49_1, R40_10-14) were analysed with the 'beta' version of the Root sort code for
event
reconstruction (/homes/npg/AIDAsort/). The code creates events from data bits that fall within a window of
50usec, and included the additional requirement that the calibrated energy of each ADC hit should be E>1500
keV.

A few plots from these data:
R49few_a_bckgrnd_multiplicity.png: Shows the multiplicity of reconstructed events. Peaks corresponding to
multiples of 64 are clear from pulser (64 ch/asic, although one FEE has some channels off so peaks shifted).
There is also peak at low multiplicity where gate to search for events can be placed. The events with very
high
multiplicity indicate the time window used is too large, so we get random coincidences or high count from
noisy
channels. The lower plots show how the energy sum increases linearly with the multiplicity of the event
R49few_a_bckgrnd_xy.png: Plots for the calculated mean strip for hits on each side (<x>: nnaida#11 and #12,
<y>:
nnaida#13 and #14). The different plots have different condition applied. Top left only requires
multiplicity on
x and y greater than zero (i.e., a hit for each side). The others require low multiplicity, or low spread of
the
timestamp of the hits included (spread dts<10usec), and also mask out hits with x value of 18 or 101 (very
high
count channels)
R49few_a_bckgrnd_dt_event.png: The difference of the time-stamp for hits with lowest and highest time-stamp
within each event. 50 usec is the event window considered (so highest possible value). Note that events with
multiplicity 2 (1 hit in x, and 1 hit in y) have almost exclusively a spread of very few clock cycles.
R49few_a_bckgrnd_EfEb.png: Energy front vs energy back spectra, with some of the conditions described above
(e.g. low multiplicity, or multi=2, low spread in time-stamp). All have hits with x=78 and 102 excluded. The
most clean spectra is top-right (one hit in x, one hit in y), but shows only a couple of hits with good
energy
in both sides. |

Fri Oct 24 16:02:26 2014, Alfredo Estrade, bench tests with pulser
|
Performed pulser measurements with test setup at Daresbury lab, with main purpose of remembering how to operate the system! The status is similar to what Chris observed in Elog entry #14. Confirmed ASIC settings as in entry#4 of elog.
The pulser spectra shows FWHM of ~ 13.5 ch for all FEE64 cards with no DSSD connected to the system (i.e. Kapton cables unplugged). Some channels in a few FEE64 cards show two peaks on the pulse spectra, but still narrow and only slightly wider distribution for the two peak combined (~ 15 ch, see Figure 1).
With the DSSD connected, the pulser spectra shows a double peak structure with FWHM ~ 250 ch for each peak (Figure 2).
However, for NNAIDA#11 and #12 a few ASICs had high level of noise, and were therefore used in the 1GeV range to become quiet (ASIC3 for nnaida#11, ASIC1 and 2 for nnaida#12). Figure 3 and 4 show sample of these noisy channels.
A good question brought up by Patrick is if the true noise level with a biased DSSD corresponds to these 'noisy' ASICs, or to the ones that are much more quiet (maybe some signal path disconnected for these?). Measurements with a radioactive source could clarify this.
Figure 1: pulser, no DSSD connected
Figure 2: double peak structure for pulser spectra for NNAIDA13 (similar spectra seen in the other FEE64 cards)
Figure 3: spectra for NNAIDA#11 with biased DSSD connected, and no pulser signal going into the system (only noise)
Figure 4: spectra for NNAIDA#12 with biased DSSD connected, and no pulser signal going into the system (only noise)
