TD, Updated Patrick | CAEN N1419 HV output common mode noise |
There appears to be significant common mode noise on the output of the
CAEN N1419 4 Ch Reversible 500 V/200 µA NIM HV Power Supply Module (USB)
- the specification quotes 'Max Ripple smaller than < 5mVpp'. We configure
the CAEN N1419 outputs as floating wrt NIM module/crate chassis.
For example, attachment 1, shows the output of module #2 (Addr 01) channel #3
(unused channel) set to 10V (leakage current 0.030uA) - core (Ch 1)/braid (Ch 2).
Tektronix 3034C channels 1 & 2 are both set ac/1M.
Attachment 2 shows math function Ch 1 - Ch 2 (50mV/division cf. 200mV/division
for Ch 1 and Ch 2)
Attachment 3 shows CAEN N1419 #2 settings
Attachment 4 per attachments 1 & 2 *except* the cables from channels 0 and 1
of CAEN N1419 #2 have been disconnected from the NIM module. The structure of
the common mode noise changes but its amplitude remains significant. This
presumably indicates that there are other sources of common mode noise in
addition to that observed at the output of the CAEN N1419 HV outputs.
Attachments 5 & 6 show the NIM crate front panel +6V output wrt ground
for the lower (NIM Bin type REPIC, BNC PB-4, Ortec 433, 2x MACB, 2x CAEN N1419,
1x CAEN 1419B) and upper (NIM Bin type OKEN, 9x MACB) AIDA NIM bins respectively.
All +/-24V, +/-12V and +/-6V front panel outputs show the same noise structure.
Attachment 7 shows equivalent of attachment 6 but using Tektronix DPO3054
which can display FFT.
Update -----------------------------------------
Tested the CAEN HV supply in T9 using the same method and observed similar results.
With help from Mos Kogimtzis a better method of measuring the HV noise was used.
The co-ax from the isolated output of the HV module was connected to one input of the 'scope. HV set to 1V.
Thus the screen of the HV signal is grounded at the 'scope amplifier input. This nearer to how the HV is used with a detector.
The single signal input channel was set to DC 1MR with an offset of 1V.
The 'scope can now display at 4mV/division.
The peak/peak was less than 5mV.See attachment 8 slide 1
There are features at both high and low frequency, attachments slides 2 and 3. NB 1mV/division.
If a differential measurement is required then a suitable cable with a shielded twisted pair is needed.
Update #2 -----------------------------------------
Moved the AIDA T9 HV supply to a CAEN NIM bin. Newly purchased this year.
This is the only module in the bin.
Used the simple method of noise measuring as before with the same cables and 'scope.
Attachment 9 shows there is a different type of noise. Not regular like attachment 8 but more random and larger.
The HV is set to 1V.
Further investigation will be carried out using AC coupling and HV set to 50V. |

DK | Simple PID with LISE++ | I wrote this LISE++ file based on the Takechi .lpp modified by AE for 77Ni, 78Ni, 76Ni.
Basically, I changed the primary beam to 48Ca, reduced the production target thickness to 1 mm (I think it may
be correct), inserted the carbon target at F8, and made the RIB as 41Al and had it calculate the optics. Then I
modified by hand D7 and D8 Brho settings to like 6.32 Tm which is something near the correct value (for plastic,
but I forget for carbon, slightly different perhaps?)
Then I make a fairly arbitrary dE-ToF plot (attachment 1) without any concern for what data it thinks is filling
the plot, and run the Monte Carlo simulation.
This may give a user some kind of naive picture of what sorts of ions we might expect, with a basic clue about
their relative intensity or improbability to detect.
I did this work in literally about 5 minutes total, so do not take it too seriously. It is definitely not
right, but it is not totally nonsense either. You can play with the .lpp file (attachment 2) if you want to
improve it. You should definitely get the degraders used within BigRIPS correctly. I imagine they are much thicker, because D6 being 8.42 Tm is much too high (it was more like
7.5 Tm or so?) The other things you can (and should) add is things at F11 like our degraders, AIDA, and so on. I heard Gabor might do this at some point, but he may have become
very busy with other tasks.
Attachment 3 shows some relative intensities numerically. Again, you should not really trust this.
However, let's take some known experimental values.
I recall that at the BigRIPS F11 Pla. scaler, when we did the 41Al unreacted measurement, it was about 30 cps = 108000 counts per hour
I think we had about several counts per hour of 40Mg in the best case reaching to F11.
It means that 41Al and 40Mg ratio is around order 10^5 difference.
Surprisingly, this is nearly the same as the results of this quick LISE++ simulation (attachment 3 has numbers) |

DK | Benchmarks for compression | R45_17 as the test file, which was closed at 9.02 AM Friday, December 2nd at the end of the official parasitic
machine time on Fallon et al.
===Summarized results===
Initial file is 2.0 GB of AIDA data
LZMA: 862M; Time: 23 min
BZ2: 1.3G; Time: 6.5 min
GZ: 1.3G; Time: 3 min
The LZMA results are about as I expected: fantastic compression but it takes a very long time to pack the data.
The BZ2 data are a bit surprising; usually it can be about 10 or 15% smaller than GZ for hexdata from my
experience. I conclude that we should use GZ (which we are already doing, but now we confirm that it is
optimized for time versus disk space usage).
15.49 We are continuing to compress the data. Presently we are somewhere around R39_20, sequentially. I
estimated that there are 578 runs remaining, and naively say each is 2 GB (some at the end of RXX_ may be less).
Compression at 3 minutes each then takes 29 hours, so it should be finished by tomorrow evening, say around
20:00 or a little later, depending on the fluctuation.
===Full details of the test===

See attached histograms.
Figure 1: The time structure of low energy events seems more normalized with a flat-top and similar intensity as
like R41_2 (see i.e. https://elog.ph.ed.ac.uk/AIDA/507 ) rather than R42_32, though one wonders if this is a
real effect or if R42_7 was somehow unusual.
Figure 2: We can confirm that the number of real events corresponding to light ions seems reduced compared to
R42_7 Fig 4.
Figure 5: Distribution in XY of low gain [heavy ion / high energy] is still weighted to the right hand side as
usual, but seems slightly more homogeneous than previous cases such as R42_7. This is corroborated by the
scalers pasted above, where the implant rate to DSSD#3 is about 0.3 Hz rather than 0.4 Hz of R42_7; this is
probably a real decrease and not merely a statistical effect as R41_2 also shows around 0.4 Hz. I conclude that
heavy ion implant rate is reduced by about 1/3 from R42_7, most probably from the Pb bricks cutting some
fraction of the beam (though in theory it could be from shifting 5 mm of the Al degrader up stream by ~2 m and
the angular straggling of the heavy ions in the plate).
Specific comparison of the implant rates show we are dropping 0.1 cps on DSSD#2, 0.1 cps on DSSD#3, and maybe 0.05 Hz
(it's a sensible number or not different than zero?) in DSSD#4, which can give an idea of what ion species are being
cut out if we looked at the BigRIPS PID correlated with AIDA implantation. |

Figure 5 shows low energy front and back, and if I compare to R41_2 offline analysis (i.e. https://elog.ph.ed.ac.uk/AIDA/507 ) then we see more fluctuation (of light ions?) it seems. Run 41_2 seems to show mostly noise (anti correlation) and here we see real ions (positive correlation. This is confirmed in our figure 4, where the statistics of DSSD#3 seems about doubled. The event rate per unit time in 41_2 shows a relatively flat top behavior characteristic of noise domination, where as our present one shows more jitter that could be characterized by light ion production and transport variation.
