Core Simulation

• G4 simulation LAr stepper dispatcher. This intelligently selects EM field look up frequency, type of stepper, and the stepper precision based on particle type, kinetic energy and subdetector. This results in a >10% speed-up on ATLAS full simulation.

• Learning core ATLAS Geant4 support and release validation (aim to replace Z. Marshall 1st Jan 10 onward)

Inner Detector

• Helped create readout of pressure and temperature sensors introduced in the distribution rack upgrade. Created the DCS software in ID ENV project that supports the distribution rack panels in EVCOOL, including FSM calculations and automatic setting of alert thresholds.

• Fixed errors in ENV introduced by the migration to PVSS 3.8.

• Improved ENV user interface, tidying up data presentation and making panels easier to navigate.

• Participated in the "leak down tests", monitoring pressure drop in sealed, pressurised cooling loops and subsequent data analysis.

• Repaired the TEH project, overhauling the FSM and replacing faulty code.

• Shifts, both as "expert on call" for the cooling projects, and as regular SCT shifter.

Upgrade Simulation and Computing

• Studied the performance bottlenecks in ATLAS computing
• Helping with the design of ATLAS upgrade simulation & computing
• Starting on 15 series sLHC release validation

Distributed Computing

• Supporting UK sites involved in Distributed Data Management (DDM). Built up necessary expertise and now supporting sites through wiki pages and discussion forums.

• Developing and maintaining new Disk Pool Manager (DPM) tools for ATLAS needs. Wrote new tool to replicate files within the new ATLASHOTDISK spacetoken, and starting work to determine missing or corrupted files within ATLAS spacetokens at DPM sites.

• Developing monitoring tools for DDM. Begun working within the current dashboard "sandbox", expecting to integrate this work into developing plans for the ATLAS dashboard monitoring.

• ATLAS Distributed Computing Operations (ADCoS) shifts. One group member has completed multiple training shifts and is now progressing to "senior" shifter. Another group member has started the training process.

Event Generation / Min Bias

• Herwig++ Athena interface development and maintenance

• Lead Herwig++ validation effort for W, Z production (LO & POWHEG), SUSY simulation, and QCD

• Tuning of Pythia 6 for MC09

• Early data retuning task force
