IOWA/Fairfield + Any Others Proposed Tasks
Task 1: New Tiles based on Quartz Armatures (FY 14)
A) Scintillator Films on Quartz Tiles
- (ZnO:Ga; CsI; CeBr3 – emissions 375-450 nm; T<17ns)
- CsI and CeBr3 will be protected with an over-deposited quartz film
≥50 nm thick.
- TIR cladding layer: 20 µm of Polymicro HardCoat (as used in HF
fibers).
1. Double-sided Single Plate: coated 300µm≤ 3mm thick tiles
(thickness & optical finish chosen for the lowest cost, up to 3mm
thick), 10 x 10cm; coating thickness up to ~10 µm. Minimum 2
Tiles each of 2 downselected materials. Readout: WLS fibers.
2. Sandwich: ≥300µm thick quartz tiles as above, 10 x 10 cm, singlesided coating, but assembled in stacks up to ≤3 mm thick. Film
thickness: 5-10 µm. Preferred deposition: e-beam evaporation.
Minimum 2 sandwiches each of 2 downselected materials.
Readout: WLS fibers, one per edge.

Quartz Optical Clad Capillary - Thin Films on Fibers
Due to the limited available funding we are only
requesting funding for the Task 1 which is $40k at this
stage. We assume that we can only act on Task 2 if
there is further funding in 2014.
Our full funding request and plans including FY15 are
included in the appendix which can be also found
below:
https://indico.cern.ch/event/313304/
 TB Forward Calorimetry at CERN H2- Oct 15 for two
weeks (B.Bilki-Y.Onel Co-Spokesman)
 T-1041 Forward Calorimetry at FERMI (B.Bilki-Y.Onel CoSpokesman) last test beam for FY 14 is 2 weeks in July 14.
We are scheduled for an additional 8 weeks in FY15
(Starts in Oct 14). We are planning 2 weeks in November
and 2 weeks in December 2014.
 CERN PS IRRAD facility ( IRRAD 2, 5 and 7) we are
scheduled for 2 weeks (J.P Merlo-Iowa leading)
We will be using Iowa, FERMI and Fairfield facilities and we
want to have an “Access to Deposition/Commercial Services” if
funding is available.
If funding is available on time- We can test these in the TB at
CERN and FERMI in year 2014.
