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
