Introduction

BTV DescriptionA radiator is inserted into the beam path.The interaction of the particles with the material generates light. A camera system captures the light through a viewport. The image corresponds to the beam ‘footprint’ on the screen. It is used for beam observation, steering or measurement.

Actual situation (1)

Mechanics → non BTV standard- 5 old ‘Marguerites’ (ageing and no spares)- Only used as screen holder (not target anymore)

6 F61N.BTV02. Upgraded in 2014.

Actual situation (2)Electronics- BTV VME board controls → already BTV standard

- Camera- Lights- Image acquisition- Filter wheel - Screen insertion device

- CAMAC Marguerite controller → non BTV standard

Application- BTV application → BTV standard

- based on FESA classes already in use by all other BTVs installed in the all accelerator chain

- GM class software → non BTV standard

Maintenance- Requires the input of 3 groups:

- EN-STI for the mechanics- BE-CO for the actuator control - BE-BI for the camera acquisition

Upgrade:- Get rid off the old Marguerites- Get a BTV design (new screen insertion

device with a newer vacuum chamber)- Use the standard BTV hardware CTRL

and application

- For optimization reason regarding development, installation, maintenance and operability, a unique monitor is developed for the 5 BTVs with minor modification to fit with each position and application

New Mechanics BTV (1)

Screen- Tests made on different PS beams on the extraction line F61, confirmed that a unique screen made of

Al2O3:CrO2 is sufficient to see the whole range of beam intensity extracted into the East Area.- Material : Al2O3:CrO2 (luminescence) 1mm thickness

- Marks : the screen will have marks only on the outside of the region of interest to optimize the S/N during measurement

- Size: Screen

Screen Insertion DeviceA magnetic coupled push-pull device was chosen from UHV Design (model MPPL-150) as the screen insertion device. This actuator will be driven by a pneumatic device from SMC (model CDG1BN32). This new actuator system is already in the pipeline for being used in the new BTVs for the ELENA machine.

New Mechanics BTV (2)

Vacuum chamber- Taking into account the space needed by the instrument in all locations, the

vacuum chamber was designed taking into account the smallest space available to guarantee that it fits in any of the 5 locations:

- Longitudinal length = 304mm

Vacuum Interconnections- ‘KF250’ SPS type on the BTVs

- Either connection with or

Support, alignment table- The support and the alignment table are developed by EN-MEF and will be use as a

standard in the F61 line- PSZBTVMC0001 already validated for production

Mires system- The mire system is attached to the same flange than the screen insertion device

which permits to optimize the metrology (one can get the screen position wrt the mires, avoiding any metrology on the vacuum tank). The mires system stays in the BTV to optimize time in the machine for any survey.

Total 192

Even if quite challenging from the beginning, we try to keep planning installation as : - 4 BTVs: in the PS during YETS 2015/16 (end of January, beginning February 2016)- 1 BTV: inside the primary zone, later in 2016, before the start up of the East Area (to

benefit as much from the radiation decrease)
