Cryostat frame
Project
With the development, production and assembling of an extremly light weight and vibration damped construction frame had Heinz Baumgartner AG a further opportunity to produce a important part for the SwissFEL grounds of Paul Scherrer Institut (PSI).
The construction is made for a Cryomagnet system for the Swiss FEL test centre at the Paul Scherrer Institute (PSI). The goal of this whole system is to examine quantum materials at low temperature and high intensity magnetic fields. The laboratory setup will be installed at the Bernina and Cristallina end station and used for X-ray scattering experiments.
Our service
Based on a topology optimization and a raw concept of the construction design, made by PSI, the project started at the engineering department of Heinz Baumgartner AG. With the given calculations and requirements it was possible to develop a more detailed concept. To ensure the construction will have enough stability it was necessary to develop a junction made out of aluminium, which enabled an adhesive connection with carbon tubes.
The concept study and the adhesive connection was verified through a prototype, which was built at Heinz Baumgartner AG. Therefore the company had to produce the aluminium parts in their own production und assemble them later. After the assembling, the 1.5m tall frame had to be installed on a special “dummy” plate to simulate the special terms under which it has to work as part of the Swiss FEL Experiment. The whole construction is 130kg in weight and managed without problems to work under a pressure of 630kg during the acceptance test.
In collaboration with PSI and Heinz Baumgartner AG had to fulfil a diversity of tasks, including the development of constructions, production of the prototype and single parts, as well the gluing of the frame casing at its assembling. For this, a variety of expertise was required from the company.
Project
In mid-2015, Heinz Baumgartner AG took over the construction and assembly of a photon spectrometer (PSSS, Photon Single-Shot Spectrometer) for the SwissFEL large-scale system of the Paul Scherrer Institute as part of the Aramis beam line.
Our Service
In addition to project management tasks, the scope of the project included the production of individual parts and the processing of high-purity stainless steel alloys for vacuum components. A special feature was the production of a so-called Beryllium domes that were manufactured, tested and finally completed by a supplier in California (USA) in several process steps by applying a wafer-thin beryllium foil. The entire spectrometer, consisting of two independent units (Grating Unit & Spectrometer Unit), was completely assembled and set up at Heinz Baumgartner AG. Crucial components were precisely aligned and measured at Heinz Baumgartner AG, all linear and rotary drives installed were tested. The delivery to PSI took place at the beginning of April and the spectrometer is currently being put into operation by the responsible researchers at PSI.
The function of the spectrometer is to measure the photon spectrum of each individual X-ray light pulse. It provides important information for the system control and for the users of the SwissFEL.
With this project, Heinz Baumgartner AG has for the first time moved into a completely new area of machine and apparatus engineering, namely the construction of a system for research and development. Thanks to the close and always constructive cooperation with PSI, the project was completed extremely successfully and on time.
