ORNL Group (Background)

Involved in CERN Heavy-Ion program since its inception in 1985:• WA80 experiment:

• Built EM/Had Total Energy sampling calorimeter (MIRAC) in collaboration with LBNL, Lund, and GSI. (Awes, Young).

• Built Zero Degree Total Energy Sampling Calorimeter. (Young)• Built custom Transverse Energy trigger for MIRAC used as basis of WA80

MinBias and centrality triggers. (Awes).• Primary responsibility for operation and calibration of MIRAC. (Awes).• MIRAC data analysis. (Sorensen, Awes)• and Direct Photon analysis. (Awes, Stankus)

• WA93 experiment: • Same as above for WA80, and in addition…• Built custom electronics for a high resolution BGO photon spectrometer

prototype (20-bits effective range) - intended for WA98 but not implemented beyond prototype in WA93. (Awes, Stankus,Young)



• WA98 experiment:• Used MIRAC and MIRAC ET trigger.

(Awes, Young)• Primary responsibility for operation and

calibration of MIRAC. (Awes)• MIRAC data analysis. (Awes, Sorenson)• Built custom electronics for 10,000

element PbGlass photon spectrometer (LEDA). Dual gain ranges, single shower trigger, proto-type for PHENIX EMCal. (Awes, Stankus, Young)

• Spokesperson - second run, “publication phase”. (Awes)

• and Direct Photon analysis. (Awes, Stankus)

WA98 nucl-ex/0006007, PRL 85 (2000) 3595.



• PHENIX experiment - hardware, operation• A “Founding Father”, deputy project manager (Young)• Trigger/DAQ structure (Young)• Responsible for design, construction, installation, operation of Muon ID

(Awes, Cianciolo, Efremenko, Stankus, Young)• RD10 AGS beam studies of background for muon absorbers

• Designed / Built MuID electronics (Cianciolo, Efremenko, Young)• Various contributions to electronics for MVD, MuTr, PC, and RICH

(Silvermyr, Young)• Responsible for installation, operation of PbGl EMCal in PHENIX (Awes).• Designed / Built EMCal Readout Electronics (Awes, Stankus, Young)• Detector Council (Awes, Cianciolo, Young)• Run coordinator for Run 4 (Awes)



• PHENIX experiment - physics• Terms as co-Chairs of Physics Working Groups (Awes, Cianciolo, Silvermyr, Stankus)• Executive committee (Cianciolo)• 24 Paper Preparation Groups: Awes 3, Cianciolo 7, Read 1, Silvermyr 5, Stankus 6,

Zhang 3.• 6 Internal Review Committee: Cianciolo 2, Read 2,Silvermyr 1, Stankus 1, Batsouli 2.• 72 Analysis Notes: Awes 15, Cianciolo 17, Read 13, Silvermyr 17, Stankus 10, Zhang

Past ORNL effort on ALICE

• ORNL ALICE contributions pre-dating ALICE-USA (as PHOS collaborators raised emphasis on high pT):

• Instigated PHOS decision to switch from PhotoDiode to APD readout. • ORNL responsible for PHOS readout conceptual design - large dynamic

range (100GeV vs 10 GeV), trigger capability and trigger design,…• ORNL (+ BNL) originators of EMCal proposal - obtained ALICE approval.

• Contributed significantly to preparation of various EMCal documents.• A Proposal to Study Relativistic Heavy Ion Physics with the ALICE

Experiment at the LHC - March 2002.• ALICE-USA Report to NSAC/DOE - May 2004. • The ALICE Technical Proposal Addendum 3: Electromagnetic

Calorimeter - April 2006.• The ALICE Electromagnetic Calorimeter Conceptual Design Report -

September 2006.


Recent ORNL effort on ALICE

• ORNL Seed Money 125k$ FY2005 for EMCal electronics effort and test beam effort.

• Organized first EMCal testbeam measurements at FNAL Fall 2005.• Assemble all components for readout of 64 EMCal towers.

• Repair/modify spare PHOS FEE cards for EMCal• Purchase and setup of ALICE DAQ

• Define program of measurements, arrange testbeam facilities, testbeam trigger detector readout, organize manpower,…

• Oversaw data analysis

• Overall responsibility for EMCal readout electronics (Awes)• Adopt PHOS readout to EMCal - FEE shaper modification • Geometrical layout - FEE Crate, Tower to FEE mapping, Trigger inputs• Specification of electrical services - LV, HV, cooling requirements.• Cabling specification - Layout, Connectors, Patch Panels

• LV, HV, Ethernet, Trigger In and Output, Fiber clock and readout, Temperature

• Service cable purchase and installation - currently being completed


Recent ORNL effort on ALICE

• Responsible for APD+Preamplifier purchase, assembly, and test procedures • First APD+CSP test station currently being implemented at Catania

• Coordinate with Hans Muller (PHOS/EMCal engineer@CERN) modifications of PHOS FEE for EMCal:• FEE cards -

• Currently producing 10 FEE cards of final EMCal design for next test beam

• Trigger - • Will use PHOS Trigger Region Units with modified FPGA code• Working with Grenoble engineers on implementation of Jet Trigger module that

will use TRU outputs

• CSP Transition cards:• Working with Nantes engineers to design EMCal T-cards

• FEE crate backplane IPCB and GTL bus• Working with Nantes engineers to design

• LED Calibration System - • LED Driver - with Hans Muller


Current ORNL effort on ALICE

• Complete design of EMCal readout, I.e. continue all of the above.• Awes planning to go on assignment at CERN in September 2007

• Prepare for test beam in fall 2007 at CERN with pre-production (final versions) of EMCal modules and electronics

• Responsible for EMCal Online control, calibrations, and monitoring (Silvermyr)• Silvermyr on assignment at CERN since January 2007 to become familiar

with ALICE DAQ/Database “environment” and to assist installation work• Implementation of Database interface for Online controls underway

• Common solution for PHOS and EMCal

• Working with First PHOS module to assist with (also J.Hamblen of UT)• FEE configuration/control/testing, e.g. zero suppression• Cosmics measurements

• Calibrations• Single shower (TRU) performance


ORNL ALICE Activity Summary

Technical responsibilities will largely occupy 2 staff (+postdoc) -

• Electronics: Complete design, manage purchase, assembly, and testing components of readout of supermodules. (2007-2011)

• Detector: Participate in assembly, testing, calibration, installation and commissioning of supermodules. (2007-2011)

• L0/L1: Commission single shower trigger; participate in its testing and commissioning. (2008-2011)

• Online: Preparation of online control and monitoring software, time-dependent calibrations from LED monitoring data, calibration software. (2007-)

• Analysis: Extraction of neutral pion and direct photon spectra. More as manpower permits… (2008-…)
