LA Tech on LDCTook part in drafting current Detector Outline Document (DoD)Co-Editor of Supplementary Tracking chapterIncludes some simulations results obtained at LA TechSimulation Wars: Two ways of generating detector simulationsSLAC: STDHEP input => SLIC GEANT interface => org.lcsim reconstructionDESY: STDHEP input => MOKKA GEANT interface => MARLIN reconstructionWe have worked on geometry in both MOKKA and SLIC frameworksBoth branches use LCIO file format for outputE.g. Should be able to reconstruct SLIC output with MARLINWe are testing this at LA Tech. Detector R&D collaborationRecently joined the LC-TPC collaborationCommon interest in gaseous detectors (GEMs, micro-megas)Development of ETD cannot be independent of TPC endplate design

Recent LCRD ProposalJoint proposal with Oklahoma (Strauss), Indiana (van Kooten) and LA Tech (Sawyer, Greenwood, Wobisch; Wells)First step in a possible Forward Tracking R&D collaboration a la CALICE or LC-TPC.Continuation of previously described work at LA TechAssistance from OK and IU in test beam, electronics developmentYear 3 of 3-year renewal cycle. Strong new effort from OK in forward tracking algorithms. Collaboration in detailed forward studies, incl. low angle forward tracking (i.e. FTD).

A HV-PP4 is therefore not only capable of a current measurement of the HV-lines on a single module level (by the use of ELMBs), but it is also responsible for the correct mapping of the iseg HV channels to the detector modules. 16 HV-PP4 crates will be required for the experiment, each with up to 117 monitoring channels.

LTU Site ReportDick Greenwood

Current MonitoringThe circuitry included in the HVPP4 design contributes to this protection system by sensing the current flowing through High voltage cables and making the reading available through ELMB to the DCS.

2001 plan: Dallas to AtlantaIt was the equivalent of watching the transcontinental railroad being built and not coming through your state. Before the NLR would change the design to come through Louisiana, we had to convince them we were serious players
