Your tasks

In the frame of Isotope and Muon Production using Advanced Cyclotron and Target Technologies (IMPACT) project, three new beamlines will be built at PSI in the High-Intensity Proton Accelerator Complex (HIPA). Two of these lines foresee the increase of the muons production rate by a factor 100, allowing a significant improvement of the quality of the experiments. These lines are solenoid-based and the assessment of the solenoid magnetic axis is a crucial point for the magnets alignment in the beamline. For the series production, the main system for axis measurements is a field mapper based on a 3D Hall probe transducer. Field mapping measurements of large aperture solenoids is a time-consuming task. The typical uncertainty of the axis assessment is 200 µm, enough for the alignment of the device in the machine. However, axis measurements using another technique would be useful for cross validation. In this regard, a new method based on sliding fluxmeters can provide a fast and reliable way of measuring a solenoid’s axis with improved accuracy. An important component of such a system is the actuator for the longitudinal motion of the fluxmeter. The main requirement is to achieve high speed for best SNR with minimal vibration to avoid spurious signal.

In the framework of the implementation of a new measurement bench based on the sliding fluxmeter, the objective of the work is the design of the high-speed actuator for solenoids measurements with sliding fluxmeter. The main tasks related to the internship are:

Review of the existing solutions
Define the requirements for the new actuator
Mechanical design of the tool
If required carry out simulations to assess immunity to vibrations
Prepare 2D drawings for manufacturing
Commissioning of the SW on the new vibrating wire bench
