Press Device Collaring/yoke-integration press The ASG press device is one used for the fabrication of the LHC cold masses. It is mainly composed by: - A sliding bench that allows the insertion extraction of the assy to be pressed A serie of hydraulic jacks that press the object from the bottom to the top A reaction beam on the top that contrasts the pressing force For the subsequent applications i. e. for SYS 300, for the D 2 -Model and then for the D 2 Prototype the device is revamped and adapted to the new situation. In the actual configuration: i. e. 8 hydraulic jacks can press till to 2000 tons. Application: it is used for both collars assy than for the yoke integration by inserting a dedicated set of spacers.

Press Device Collaring/yoke integration press A) Collaring of the single aperture (for the D 2 Model 3 cylinders acting simultaneously 1° aperture 590 bar; 2° aperture 600 bar) October 02 2019 – ASG Superconductors Confidential www. asgsuperconductors. com 6
Press Device Collaring/yoke integration press B) Integration of the iron joke halves (for the D 2 Model 4 cylinders acting simultaneously was necessary 300 bar) October 02 2019 – ASG Superconductors Confidential www. asgsuperconductors. com 7
Press Device Collaring press – actual status At present the press works manually by acting onto the pumping device. All the jacks work in parallel i. e. the force is equal for everyone. No possibility exists to adjust the single cylinder force (only the possibility to exclude one or more jacks). An analogic pressure gauge indicates at which pressure level you’re working. The overall force is given by a table pressure vs. force. No data recorder is actually present. October 02 2019 – ASG Superconductors Confidential www. asgsuperconductors. com 8
