Setup for the hypernuclei experiment

• Remove target, MVD and backward endcap

• New beam pipe, targetsystem, germaniumarray

DCS of Primary Target?

M. Bölting (HIM) 5

Primary Target Motors

• Host: Beaglebone Black withdebian 8.4

• Running EPICS from Repositories

• Controlled via streamdev

M. Bölting (HIM) 6

Primary Target

• requires Luminosity feedback forpositioning

• Sledge motor problematic -hardware redesign

M. Bölting (HIM) 7

New Hardware

M. Bölting (HIM) 8

Ordered, but still missing:

• Sledge motor

• Rails

• No working setup

Position Control

• c position: ±50 μm

• Precision of approachunknown

• Up to 15 m light guide

Z Movement Hardware Interlock

• Distinguishable Position usingBeagleBone Black ADC

• Read via devgpio

• Hardware Interlock possible

Primary Target DCS

• Target exchange

• Luminosity controlledMovement (simulated)

• Integrated z Position control

• Essentially working

M. Bölting (HIM) 11

Summary

• Hypernuclei DCS 3 parts

• Primary Target: Prototype done (no Luminosity feedback)

• Secondary Target: similar Hardware to MVD strip part

• Germanium Array: Development ongoing
