5. 23 July, 2003Curtis A. Meyer5 Present Manpower P. Smith (IU 100% - FADC, C.W. bases) F. Barbosa (Fast Electronics 30% - TDC, FE electronics) Ed Jastrzembski (DAQ 80% - TDC) David Abbott (DAQ 60% - TDC) James Proffitt (Fast Electronics 30% - TDC) Jeff Wilson (Fast Electronics 20% - TDC) David Doughty and students (CNU 20% - Trigger) for Electronics

6. 23 July, 2003Curtis A. Meyer6 Accomplishments F1TDC – 32/64 Channel Prototype built. - Will be used in both Hall C and Hall B FADCs – 1 channel 8-bit, 250 MHz prototype built. Detailed Trigger and Rate Studies Carried out - High speed network tests into phase 2. Robotic Electronics Facility at IU installed last month and is starting to run.

7. 23 July, 2003Curtis A. Meyer7 Front-end Accomplishments Cockroft Walton bases for Pb Glass PMT used in the RadPhi experiment. Studies of Hybrid PMTs for calorimeter underway. The progress here is directly coupled to the status of prototype detector work.

10. 23 July, 2003Curtis A. Meyer10 F1TDC Production for use in experiments in Halls B & C. Operation will provide feedback on the design Eventual design updates. TDC design – Effort will continue at roughly half the current level through the next phase.

11. 23 July, 2003Curtis A. Meyer11 Flash ADCs Production of an 8-channel module. Testing of units with prototype detectors. Open issues in design based on the results with prototype detectors. - 8-bit, 10-bit, … resolution. - Clock speed needed. - Final density of packing FADC design – A similar effort as used for the entire TDC effort will be needed.

12. 23 July, 2003Curtis A. Meyer12 Trigger Complete test/studies with the high-speed crate interconnects. The current technology is not fast enough, but the path is clear from 160MB/s -> 500MB/s S-Link64 64-bit version of current technology Integrate XILINX into cards and PowerPC into boards to achieve 800MB/s Trigger design – continued effort at current level with additional students

13. 23 July, 2003Curtis A. Meyer13 Front-end Electronics Prototypes of both the straw-tube and planar drift chambers are currently being built. With these, we will be able to study front-end (preamps). We are currently working with Hybrid-PMTs for the barrel calorimeter. Start counter design calls for VLPCs based on D0 Design at FNAL. In contact with FNAL. Front-end design – DC pre-Amps, VLPCs, Hybrid PMTs, PMT voltage dividers. Depends on results of detector prototypes and amount of customization required

14. 23 July, 2003Curtis A. Meyer14 Production and Testing Production and testing – supervision of temporary manpower to receive, test and install Budgeted as part of construction

15. 23 July, 2003Curtis A. Meyer15 Summary To date, the collaboration has focused on electronics that are more generally applicable than the GlueX experiment. While we have accomplished a great deal, the effort has been limited by the lack of “CD0” for the upgrade project. We have a solid plan to move forward with all the electronics for the experiment.
