DOE CD-3 Approval
Mu2e Achieved CD-3 Approval on July 14, 2016
CD-3 approval gives the Project the authorization to spend all allocated construction funds.
CD-3 is the last CD approval prior to closing out the project.
The Project will begin to have Construction Readiness Reviews, which are required before the Project grants permission to begin procurement/fabrication of subsystem components.
Schedule of KPP4 of CD3 is consistent with previous estimate
Start discussing of transition phase from project to operation.

5. Contratto per moduli TS @ ASG Superconductors
Tutti i conduttori realizzati, qualificati e spediti ad ASG. I conduttori isolati al 100% (ok tranne un incidente, comunque risolto).
E’ in fase di completamento il modello – Settembre- (Fermilab ha insistito per avere un modello il più fedele possibile ai moduli da costruire).
Fermilab ha richiesto di impregnare al massimo 4 bobine per volta. I tempi si sono allungati di qualche mese.
Già da settembre dovrebbe cominciare la costruzione delle 52 bobine, raggruppate poi in 27 moduli e 14 unità. Deadline fine 2017.
INFN GENOA
will provide a partial
Support for Follow-up

Critical Current for PS cable
Siamo attualmente alle prese con la misura della corrente critica del cavo del PS. E’ molto difficile a causa della elevata corrente. Il cavo transisce nello stato normale prima di raggiungere la corrente critica.
Diversi portacampioni sono stati sviluppati con l’aiuto dell’officina meccanica
Work is in progress to conclude this part.
New holders (“hard –way bent” instead of
easy-way bent”) will be tried.

Calorimeter System
September 22, 2016
S.Miscetti, CSN1 meeting, Roma

10. S.Miscetti, MU2E @ CSN1 meeting, Roma
The Mu2e calorimeter
The Calorimeter consists of two disks with x34x200 mm3 CsI square crystals:
Rinner = 374 mm, Router=660 mm, depth = 10 X0 (200 mm)
Each crystal is readout by two large area UV extended SIPM’s (14x20 mm2)
Analog FEE is on the SiPM and digital electronics located in near-by electronics crates
Radioactive source and laser system provide absolute calibration and monitoring capability

S.Miscetti, CSN1 meeting, Roma

11. Long list of reviews on 2015-2016
TCR technology choice review, July 2015
Technical Choice  December 2015  CsI+SiPM
FDR Final Design Review  Feb 2016
DR for CD3c , Director review for CD3-C  April 2016
CD3c  June 2016
CD3c approval , July 2016
A lot of work in the last 2 years, but we finally arrived to a final decision:
We are freezing the design and proceeding with pre-production,
Module-0 and final engineering.
We will then proceed for slice test and construction period.
Only comments/recommendations from CD-3c:
 Test the “custom-SIPM” layout
 Proceed with agreement btw Mu2e-INFN
September 22, 2016
S.Miscetti, CSN1 meeting, Roma

12. Long list of “upcoming” reviews
Mechanical Review  end of beginning 2017
Construction Readiness Review 1 (sensors, crystals) 
March 2017
CRR for all calorimeter system ( mech, FEE, installation)
Summer 2017
At least 3 “dedicated” reviews with the new appointed
Oversight Committee.
A clear priority path exists:
- Conclude engineering
Proceed with Module-0, vertical slice test
Prepare Bids for large procurement
Prepare QA / assembly FNAL
Make all possible tests under vacuum
Complete Irradiation program

S.Miscetti, CSN1 meeting, Roma

13. S.Miscetti, MU2E @ CSN1 meeting, Roma
EMC Simulation
Great improvement in simulation with full digitization included.
As expected: CsI + SiPM is a good candidate also for Energy resolution!
A lot of work also on trigger and on in-situ calibration.
@ CD-3, crude hits digitization
With realistic hits digitization

Irradiation plans
Crystals tested up to 100 krad, MeV, slow neutron high rate
SIPMs tested up to 20 krad, 4x1011 n_1MeV eq/cm2
WD (FPGA OK) ADC+DCDC tested up to 20 krad, 6x1011 n_1 MeV eq/cm2
Safety factors
of 3 used so far
Electronics integration group
Increased safety factors value
from 3 to 12 while asking for 10
year lifetime.
So increases for FEE/WD are
10 for TID, 2 for neutrons.
Calculation for SIPM underway
In our requests, we have asked for travelling to Dresda and neutron FNG + Calliope. Requests could have been underestimated  we have probably to ask something additional SJ.

S.Miscetti, CSN1 meeting, Roma

16. Status of “large” bids (1)
The 2 largest bids are the ones for Crystals and photosensors
Same technique of “competitive bid” used for both bids:
 Use pre-production to rank the vendors
 Final selection with 40% cost, 60% technical
For crystals, the bid has been FNAL:
6 vendors participated St.Gobain, Siccas, Amcrys, OptoMaterial, Hilger, Khineng.
3 vendors selected for preproduction
St. Gobain, Siccas, Amcrys
Unfortunately Optomaterial offered a price that was too high, it was a real outlier, 2600 $/piece. All firms accepted have prices < 1700 $/piece
(i.e. inside our budget)
We have required them to provide 24 pieces/each for module-0.
We will receive additional 50 crystals from Amcrys as JINR (Dubna) contribution
bringing to 122 crystals the amount we will use for pre-production tests
and module-0.
 Expect delivery end of October.
 3 months delay w.r.t. our expected schedule. Milestone shift.
September 22, 2016
S.Miscetti, CSN1 meeting, Roma

17. Status of “large” bids (2)
For photosensors, the bid has been INFN:
3 vendors participated
3 vendors selected for preproduction of the Custom SIPM
Hamamatsu, SensL, FBK. Each of them will produce 50 pieces.
Expected delivery middle of October
We will take < 4 months for the evaluation.
Shorter time for QA (< 2 months)
Longer time for Irradiation and MTTF
We will reward them with a fixed prize of 22 kEuro/each
(with VAT,Shipping excluded).
Also in this case, 2 months delay w.r.t. schedule. Milestone shift.
A lot of tests done in the last months with “home-made” custom SIPM
so that preparation of QA Station in Pisa is proceeding well
September 22, 2016
S.Miscetti, CSN1 meeting, Roma

18. Status of MOA  SOW
After a long “summer” iterations, the MOA has been transformed in a SOW
(Statement of Work). The latest version can be signed by INFN president and
FNAL Director. Final round of checks with MIUR in progress.
It describes all sharing in “material” not in $$ between INFN and Mu2e.
It describes all activities and in-kind contributions from INFN side for the
calorimeter construction.
All SOW bringing money (i.e. manpower contracts) to INFN side are ready to
go and will be signed directly from the responsible parties of the laboratory,
sections or department where the SOW is addressed:
 SOW to Pisa for 2 year senior A&R
 SOW to Marconi for 2 year A&R
Due to the bid structure we have now, INFN is taking 100% care of the bid
for the photosensors. This changes/reduces our load for the sharing of crystals.
Apart preproduction for 102 kEuro (2016) next year (2017) will be dominated by
two big bids: 223 kEuro (crystals), 996 kEuro (SiPM) w.o. contingency

Steps for vertical slice and module-0 tests
Step-1: rate test with LED/Laser flasher
Instrument at least one channel of CsI+SiPM +FEE
Pulse it with fast LED/Laser system for High rate test (10 to 200 kHz)
Readout of 1 single channel first
Fanout to 20 channels, readout of 20 channel with TDAQ pilot
system at high rate;
Step-2: repeat test beam, CR data taking with full readout and TDAQ pilot system (Spring 2017)
Step-3: repeat test beam under vacuum with cooled SiPM in
large dewar with Mylar window in front of calorimeter face;
Step-4: Irradiate at 3 x flux module-0 for 1 FNG neutron area and study response with CRs (discussion with ENEA in progress).
Step-5 (SJ): If all other steps work  transport FNAL for test with pion beam at high rate.

Mechanics
Design of large structures (disks and rings) are now getting frozen.
They will be ready to go for construction after validation in the Mockup
Now the engineers are finalizing the drawings with the goal of
respecting the integration of the different components, achieving
good thermal contacts and allow for easy access and replacement.
The cooling system tightness and efficiency will be tested in Pisa.
Work is in progress also to select the best materials
for outgassing reasons
A lot of design has been therefore focused on back plate and holders.
 All these details will be finally tested in Module-0 and in the mockup.
