Hadronic Calorimeter

Run 1: Preparation, Performance, and Operations

The Fermilab calorimetry group played a major role in the preparation and management of CMS HCAL during Run 1

We held positions as the HCAL Project Manager, HCAL Detector Performance Group Convener, Operations Coordinator, and had major roles for the installation

Fermilab scientists, engineers, and technicians had major roles in the development of the readout electronics and the custom charge integrator and encoder (QIE) readout ASIC used for the initial construction

Fermilab was a major center of activity for US institutions during Run 1: remote monitoring, calibration, noise filters, software development…

The calorimeter-based expertise was used for understanding the HCAL performance, calorimeter based jet reconstruction, Missing ET, pileup mitigation, jet energy corrections. Involved in early jet based physics (dijet resonance search)


Run 1: Detector Performance and Operations


“High efficiency mirror” used in the light guide toelectrically isolate the HF PMT was scintillatingand a source of late pulsesMaterial was replaced and source of late pulseswas eliminated…

Developed software filters to reduce the effects of anomalous signals in HBHE and HF

Anomalous signals can be a source of fake Missing ET which is an important signature of new physics (e.gdark matter)

Identification and mitigation of detector problems

Run 1: CMS HCAL and the LPC

The LHC Physics Center (LPC) at Fermilab has assembled a critical mass of experts making it easier for individuals to effectively contribute to CMS

Major software effort including calibration and noise filter development was coordinated from Fermilab with involvement from other US institutions

Prompt feedback group was established at the Remote Operations Center (ROC)

The ROC had a direct link to the CMS control room and people could get service credit for taking CMS shifts

Access to engineering support for hardware debugging



Phase 1 Upgrades

HCAL Phase 1 Upgrade Motivation


The HCAL Phase 1 upgrades will address some of the problems that were found with the HPDs during Run 1 and mitigate anomalous signals in HF

HB/HE Increasing the HB/HE detector depth segmentation Providing time information for HB/HE readout (TDC added to QIE)Replace HPDs with SiPMsSiPMs eliminate HPD anomalous signals and drifting response Mitigation of radiation damage

SiPMs have high photo-detection efficiency for low light levelsLongitudinal segmentation for calibration of depth-dependent effects

HFDual readout of HF PMTs and time information (TDC added to QIE)Improved ability to reduce anomalous signals (showering near the PMT)

Replacing the full HB/HE/HF electronics readout chain to increase the data bandwidth.HCAL trigger will have greater segmentation and capabilities
