FNAL Calorimeter and Precision Timing Generic R&D Future

Jim Freeman FNAL Detector R&D Review Oct 29, 2014

P5 Report Recommendations

• Recommendation 27: “Focus resources toward directed

instrumentation R&D in the near-term for high-priority

• projects. As the technical challenges of current high-priority

projects are met, restore to the extent possible a balanced mix of short-term and long-term R&D.”

• Recommendation 28: “Strengthen university-national

laboratory partnerships in instrumentation R&D through investment in instrumentation at universities. Encourage graduate programs with a focus on instrumentation education at HEP supported universities and laboratories, and fully exploit the unique capabilities and facilities offered at each.”

Main Themes

• We feel we have a balanced plan that utilizes our strengths
• Largely we see a continuation of the current activities
• An important opportunity for calorimetry and timing is the CMS Phase II
• upgrade. For the ECAL two technologies: HGCAL, Shashlik. Some HE

rebuild will be involved in either option. Down select will be in Feb 2015.

• FNAL wants to maximize its contribution to the Phase II calorimeter R&D.

We will continue HE rebuild R&D at full speed and continue timing layer R&D. We will ramp up on more specific R&D for the endcap replacement calorimeter when the path is clear.

HE Rebuild

• Continue new scintillator development
• WLS Fiber R&D
• Participate in radiation hardness measurements and testbeam eval
• Develop “smart megatile” concept to create integrated scintillator/SIPM

mechanical package.

Shashlik

• Develop QIE13 conceptual design suitable for a 10%/sqrt(E) calorimeter.

We note this would be suitable for CMS barrel ECAL upgrade as well.

• WLS Fiber R&D
• Electro-mechanical-thermal concepts for “SIPM” located on Shashlik
• Participate in next generation “SIPM” development, GaIP, radiation

damage and evaluation of optical transducers for Shashlik. Techniques for extending dynamic range of SIPM-like devices.

• Fast Timing Layer

HGCAL

• Participate in thermal engineering studies needed for HGCAL design
• Use FNAL expertise to develop concept of HGCAL readout chip. More of

new direction than Shashlik

• Fast Timing Layer

New Scintillator Development

• Collaboration: FNAL/Iowa/Maryland
• Study promising rad-hard materials.

– PEN – Polysiloxanes – Liquid scintillators

WLS Fiber Development

• Collaboration: FNAL/Iowa/Fairfield/INFN/TTU/Caltech/ND
• Study quartz capillary fibers
• Participate in organic doped low temperature glass fibers
• Participate in radiation and testbeam evaluations

Smart Megatile for HE Rebuild

• Conceptual design of calorimeter “Megatile” with SIPMs at outer

boundary, differential analog signals sent to “RBX” for signal summing, digitization, readout.

• Local temperature stabilization of SIPMs using Peltiers. Local BV

generation.

• Development on previous works for CMS calorimetry and Calice.

Mechanical Engineering support for CMS phase II downselect calorimeter

• FNAL has very strong ME group.
• Two areas of contribution:

– Mechanical-thermal conceptual design work on HGCAL – Mechanical-structural conceptual design work on Shashlik

• After the downselect we will coordinate with global CMS on details of

scope.

Strengthen University-FNAL Collaboration

• Hold ~10% of cal-fast timing budget unallocated. Use for

university-initiated complimentary proposals. For example proposals that would need FNAL expertise like thin film,

• ptics preparation, other ideas where FNAL could help.

Mostly SWF, some M&S.
