Run 1-10 Test

14 September 2017

Run 11 Start 18:16 (CERN time)

Faults:

adc#2 7,8 missing segments (n+n side dE)

adc#3 19 low gain (p+n E)

some strips have no noise but maybe that is OK.

Run 12 Start 11:50

Pulse switched on halfway through

Run 13 Start 12:08

Pulser on

ADC spectra:

#1 ch0 bad resolution (also pulser)

#3 ch0 low gain, ch24 low resolution

#4 ch 7 low gain only for alphas (not pulser)

TDC missing: ch 32,80,120,123

Not understood yet: 1mm detector has peak at ~1.5 MeV @ adc#3 ch20-30 (with ALL alpha events when visible , 24 looks very distorted); not visible in ADC#4 (n+n) no alpha in ADC#6 although segment.

     Photographs of chamber, diagrams, measurement, nicely organised 
     FC output from SHV to SMA, to input to CERN preamp
     Beam viewer scintillating min beam intensity?
     Irises to protect SSDs are essential since the beams will be tuned for energy case by case and not at once.
     Collimator sizes for the target ladder?
     Window view port to confirm iris settings?
     Photodiodes should be on the opposite side of the target ladder from the collimator.  

dE detector: 2083-9, 74 um thick, V_depletion=12V; V_operating=24 V

Connect bias cables 14,15,16 (dE,E,HI)

Quad Bias Supply ports 1,2,3 (dE,E,HI). There seems to be some offset voltage on them (V1=3V, V2=7V, V3=1V, V4=4V) Seems to go dowon when preamps are on.

How to protect the S2s during beam tuning?
     Can the ISOLDE operators easily restore beam optics settings or not?
     (Determines if we can do all the beam tuning at once or if we have to separate them)
     Controlable iris aka Star Wars door -- contact Simon Fox at York

Dynamic range of the preamps is only maximum 200 MeV, so we need a foil to degrade the heavy ion energy

Gain resistors for up to three dynamic range settings

Checking some server settings for the elog system regarding the email notification.

And testing updating an elog.


Testing again...

Status of Beamline XT03 at HIE-ISOLDE:

Scattering chamber (1m*1m) will be put in place in next two weeks. They are just waiting for separate crane, which will be mounted on the wall.
(Reason is, that the roof crane can only go down in the middle for XT03, because it is the end of the hall)

The scattering chamber will take place at the gray surface with all tube connector.
The end of scattering chamber is ISO 100. Do we have the right adapter for the tube to connect?

The scattering chamber, with a lot of electronics inside, has a pressure of something E-06 mbar, so our pressure should fit well.

Our faraday cup was asked to have the possibility to monitor if we getting beam or not.

Behind the scattering chamber there will be a setup for Neutron Time of Flight experiment on C15 in the end of august and on 9/10Li in the end of October 2017.
The setup length will be additional 5-6 meters (close to left end of the poster/wooden box on picture).

Offline Setup:

Offline Setup next to parallel wall will probably not be possible due to the other setup, but there is at least 2-3m*4-5m space on the wall, where the beam line points to (corner). We just have to leave some space that people can access the crane ladder.
No specific time was discussed, because the current setup has to first installed.

Alignment:

The Tools are mounted at the wall (2 points) and are setup in the corner (stand from bottom). It is an electronic system, no further details from Karl, but contact has been established.

Beam Height:

Beam height is 1.75m. We will bring our own metal frame for support. What is our height (range) at the moment?

For Offline test we can have an alpha source.

Power plug: SWISS standard à need ADAPTERs

3 normal plugs per grounded access point (with C16 fuse). For offline testing we can easily use 1-2 access points, which would be enough.

Near the installation place at the beamline are also 2 access points, which we will share with the scattering chamber. In case we also use extension to the offline ones, although safety regulation allow no cables on the floor, so we always have to use cable guides above. (I´m not sure how they deal with power cables…)

Next point: cables guide are used, so we have to bring longer BNC cables and the other long ribbon cables.

No camacs crates are spotted at the moment by Karl, which we could use.

No OIL pumps are allowed anymore at HIE – ISOLDE. Our roughing pump and Turbo pump are working without oil, aren´t they?

Grounded crates??

Expectations:

They want to have a drawing of our setup (chamber including metal frame, crates, vacuum pipes, water cooling, … maybe add work place with PC)  

And all the SAFETY Regulation papers should be prepared.

Important!!! Everything is temporary:

 There are daily changes in the setup at XT03 with scattering chamber and neutron TOF setup in the next week and when ISS chamber will be installed, the odds and ends near the wall and the corner will hopefully disappear, so we will have a better picture how much space in the end will be there.

I will visit ISOLDE in the beginning of June again to see the progress.

Forgot to ask:

Any special placement for water cooling or can we still use shortest possible distance to chamber?

I asked IT about putting the elog name into the email subject line (useful for those of us subscribed to more than one elog).  They said they enabled it for ISOLDE.  Let's test 
to see!

Another test (June 1st)

status of the setup - 07/04/2017

status of the setup - 21/04/2017

1) DAQ

We have 192 channels to DAQ working. Mirco will test the silicon detectors with an alpha source in the next 2 weeks. 

2) Vacuum

In the moment we reach 6E-6. There are still 2 tiny leaks. There will be an extra turbo for the upstream beam line which should improve the vacuum for ISOLDE purposes. 
We need to check how fast we can pump down as might need to open the chamber between tuning and beam time (detectors need to be protected from tune beam).

3) Alignment

Alignment of the sample positions can be done here (Mirco/Peter). Claudia will contact Karl about a survey team for alignment at ISOLDE. Then we can talk to them directly.

4) Shipping

We aim to ship the setup to CERN by the end of March. We will try to go over to CERN for initial setup middle of April (to be confirmed with Karl)

5) Equipment needed from CERN

Claudia will ask Karl about availability of a CAMAC crate and 2 NIM bins. 

6) Safety

Peter will order safety boots and hard hats. 
Those who do not have ISOLDE access need to attend the ISOLDE radiation protection course. 

7) Availability for Preparations

Tom not here: 25 March - 3 April, 25 April - middle June
Daid not here: until middle June ?

8) Samples CH2, CD2

Paul has new batch and should send alpha spectra soon.
