1. Mini-drawers, FE-ASIC , Integrator
and HV distribution for the Demonstrator
Tile week upgrade session
2013 February 1st
François Vazeille
Mini-drawers
FE-ASIC and associated electronics
HV distribution (option 3) 1

2. Mini-drawers
Final machining of the mock-ups: to fit the instrumentation needs
and to take benefit from the CERN tests of the Slider
(See Tile Upgrade Week 28 september 12)
In particular:
More contact of Slider
with Girder rings.
More space for readout.
 Definition of the envelop: 2

3. Definition of the envelop for the readout
(drawing sent to the other labs) 3

4. Next works before the delivery to CERN of this first train
Tests of new pipes for the cooling circuitry
(not in aluminium to prevent corrosion).
Making of the Patch Panel
with holes only for HV connectors and cooling circuitry.
Delivery to CERN by March 2013.
The laboratories will have full freedom to drill other holes in the Patch Panel
and even in the Drawers in order to implement their components.
Comments:
- The drawings were sent (late because of workshop problems !) to Bucarest for studies
and the making of 2 or 3 new train of 4 mini-drawers.
- Barcelona could contribute too. 4

5.  Progress in the insertion tools
Adjustable contacts
Finger
Basket
Slider
Adjustable contacts
Some improvements of the Slider
(See the details in the September meeting).
Design of the first Basket :
holes will be left for access to PMT Blocks. 5

6. We are making every effort to produce the Slider and the Basket
Some delays due to a failure of the numerical-control machine-tool
We are making every effort to produce the Slider and the Basket
and test them at CERN ! 6

7. FE-ASIC and associated electronics
Delivery in January of the first TACTIC chips
(12 bit ADC)
After all, the first tests will be made at Clermont-Ferrand,
by connecting the support card to a test card provided by LAPP Annecy. 7

8.  Summary  Series of chips FATALIC 1, 2 and 3
 Validation of the ″current conveyor concept″.
 Promising ″digital integrator″ for the Cesium calibration.
 Delivery of the first TACTIC.
But more works are needed to converge to the Option # 2 with a single output. 8

9.  Planning New tests of FATALIC3 at Clermont-Ferrand then at CERN,
in particular for the digital integrator (Milestone: April).
Tests at Clermont-Ferrand of TACTIC (Milestone: June).
Design of 3in1 card including DAC for electronisc calibration (Milestone: October).
Design of Mother Board 2 (Milestone: September).
Combination of FATALIC3 and TACTIC on 3in1 card (with the help of Strasbourg)
 Preliminary tests at CERN in building 175
then Demonstrator tests (Milestone: October-November).
Design (Milestone: December) and foundry of
either a new FATALIC3 with new improvements (signal shape, peaking time)
or a FATALIC4 including TACTIC and the same improvements.
 One Demonstrator in ATLAS: Spring 2014. 9

10. Space to supply 4 Demonstrators,
HV Distribution option 3
 Scheme (already shown): regulation outside the Drawers.
 New HV Bus boards (no active components)
12 channels.
A 4-layer printed circuit: External layers as shielding,
Internal layers to distribute the HVs.
- Noise killers everywhere.
Rear HV
New HV regulation crate
welcoming HV cards
LV’s
Space to supply 4 Demonstrators,
but first only ¼ is made

CANBUS

11.  Present status: rear cards, support cards, power supply
and HV Bus cards.

12.  Crate
- Mechanics ready, but for the Patch Panel.
- Rear and support cards: for 1 Demonstrator.
- Once assembled, the DCS will be adapted from the present DCS.
HV Bus cards:
- Components for 4 Demonstrators  16 cards + 1 spare.
- 1 card made and tested at 2 KV.
 Multiconductor cables (12 pairs) taken at CERN (standard specifications)
- Tested at 3 KV during several weeks.
- Ordering to do of the requested length for:
 4 different short cables: distribution along the 4 Mini-Drawers.
 Long cables to connect the crate and the Tilecal modules:
Tests to do in the building 175 with 20 m and 100 m.
 Planning
Preliminary tests at Clermont-Ferrand then in the building 175,
in such a way:
Installation on a Demonstrator at CERN on September 2013. 12
