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.

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 statusof prototype detector work.

Construction

(at JLab)

23 July, 2003 Curtis A. Meyer 10

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.

23 July, 2003 Curtis A. Meyer 11

Flash ADCsProduction 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 .

23 July, 2003 Curtis A. Meyer 12

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

23 July, 2003 Curtis A. Meyer 13

Front-end ElectronicsPrototypes of both the straw-tube and planar driftchambers are currently being built. With these, wewill be able to study front-end (preamps).

We are currently working with Hybrid-PMTs forthe barrel calorimeter.

Start counter design calls for VLPCs based on D0Design 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

Production and Testing

Production and testing – supervision of temporary manpower to receive, test and install

Budgeted as part of construction

SummaryTo date, the collaboration has focused on electronicsthat are more generally applicable than the GlueXexperiment.

While we have accomplished a great deal, the efforthas been limited by the lack of “CD0” for the upgradeproject.

We have a solid plan to move forward with all the electronics for the experiment.
