HFT development

MimoStar2 based telescope


Outline

• Our goals

• Setup

• Current status

• Problems to solve

• What next …


Our goals:

test functionality of a prototype MIMOSTAR2 detector in the environment at STAR:

Charged particle environment near the interaction region in STAR.

Performance of our cluster finding algorithm. Performance of the MIMOSTAR2 sensors. Functionality of our tested interfaces to the other STAR

subsystems. Performance of our hardware / firmware as a system. The noise environment in the area in which we expect to

put the final HFT.

Current Status

• Electronics Hardware / Hardware – All required PCBs, cables, computers, etc are in hand. We are currently working on some problems involving noise in our electronics setup. We hope to resolve this shortly and assemble and test the telescope setup in a beam run at the ALS at LBL before moving the system to BNL for the beam test.

• Firmware – The required functionality required for the test has been implemented and tested in the ways possible before a working set of detectors is used.

• Integration – The insertion tube and electronics box are in place at BNL as is the cooling system, DAQ and control PCs. Final assembly and testing of the telescope is required before we can do further testing.


Problems to solve - distortions

In the configuration with a fully loaded kapton cable we see some distortions which appear in the middle of the frame


Problems to solve - noise

• The noise doesn’t come from the DAQ system (~1 ADC)

IPHC – results from Strasbourg

Mezz. Full – chip bonded on a mezzanine card

Mezz. Part – chip bonded on a mezzanine card with part of the bonds (like for a flex cable)

Flex1 – only on flex cable in the hft system

Flex2 – two chips in parallel in the hft system
