SM18 HL-LHC. Magnet transport and handling
Friday, 17 April 2020

Marta Bajko presented:
The main goal of the meeting was to introduce to our colleagues in EN the handling and transport activities that are going to be required for the works in SM 18 related to HL-LHC.
Collaboration is needed and both teams should stay in close contact mainly to update models and geometries that are going to be handled as well as environmental requirements and constrictions. Some specific modifications for the test are done often.
A document interface between Transport and TF would be useful and was proposed.
Robin Betemps can be the link between TF and the transport team in terms of models and drawings and Tonio will provide support on the field.
Marta presented the main testing activities that will need handling activities, divided in different work packages:
WP7 and WP11 are sorted out because:
a. WP7 are small electronique equipment that are not using heavy handlings
b. WP11 as we are coming to its end and we have a “modus operandi” already established.
WP3: Include magnets in vertical and horizontal test benches.
MCBXF, D2 model, MQXF models : Test in vertical position.
We have already tested and handled magnets of this kind in cluster D, but is mentioned here to show the use of the overhead crane during the IT STRING operation. The weight of the model has to be reviewed. If the test stand in FREIA is successfully completed in Sweden, 70% of the production to be tested outside CERN. The next magnet to be tested is in few months from now together with other similar magnets that typically we are testing in Cluster D or Cluster G.
Q1/3 : Test in horizontal position
It is proposed to use for the handling the ROCLA. These magnets would not arrive before 2021. Q1 and Q3 are identical and produced and tested in the USA. Only few of them will be retested at CERN on the cluster A or F. 3D models of the cryo assembly is available. Robin Betemps will make the link between transport team for the drawings and models needed.
Q2a/b : Test in horizontal position
It is proposed to use for the handling the ROCLA. These magnets would not arrive before 2021 early 2022.
In addition to the test of the cryostated cold mass it is now planned to design and build a horizontal test cryostat to be installed in bench A2 for early stage testing of some MQXFB magnets. In discussion. To verify impact with handling.
D1, CP, D2: Test in horizontal position
A part of the D2 model magnets that are tested in vertical position in the cluster D nowadays, the cold mass D2 is planned to be tested on the bench A, F or C2. We propose to move it with the ROCLA. Modeling and integration are well advanced but not yet finished.
WP6a: SC Link
SC Link assembly to be tested in F2. Still preliminary layout. The integration of the SC Link in the IT STRING is still in a preliminary phase. It is needed to make a study with WP6A team to define which are the items to be transported .
WP16: IT STRING
One of the main targets it is to clarify how to operate ROCLA to be used for the ITR STRING. This solution has not been considered till now!
Not only to have into account the magnet layout but also the racks layout and the installation sequence.
The IT STRING will coexist with magnet testing activities in both vertical and horizontal test benches. Transport might be asked to provide support related to handling if challenges appear during this stage.
Diego Zambelli presented:
A template that will be prepared with detailed element list needed to fill the transport team requirements.
Compatibility works and studies with ROCLA for new cryo assemblies are already ongoing. Adaptations should not be difficult. To be check for the IT STRING.
There are minutes attached to this event.
