However, the scientific instrument production that CINEL is able to work out, includes not only the sphere of nuclear physics but spaces within the main national and international scientific research fields.
Today CINEL, a Company exclusively oriented to the production of precision and vacuum mechanics, can boast a wide experience with advanced projects applied to the fields of biomedical physics, cryogenics, superconductivity, astrophysics and space.
Thanks to the experience achieved during several years of continuous presence in the market, the growing availability of highly specialized human resources and the considerable technological investments, CINEL has grown to such an extent that its latest activities reach the highest levels in scientific instrument production.
Very few companies in Italy are able to propose turnkey solutions to satisfy clients both from a technical and economical point of view.
CAD-CAM environment and CNC machines allow CINEL to develop independently whole technical projects, as well as their details and all subsequent adaptations or implementation of mechanic and electric pieces.
Professionally bound to the major research institutions in Italy, such as INFN, CNR, the University and Astronomical Observatory of Padova, CINEL in the last years has crossed the frontiers with projects carried out for other internationally renowned scientific bodies: CERN-Geneva (Switzerland), ERSF-Grenoble (France), JET-Abigdon (England) and GSI-Darmstadt (Germany).
Rotator Adapters: main steps of manufacture
The construction of the two derotators for TNG has represented for CINEL an important technological challenge. After the development of the construction drawings, based on the NTT experience, a detailed manufacturing plan has been produced. It included material purchase specifications, preliminary and final heat treatments and welding plans to guarantee an high deformations control and maximum reduction on internal stresses.
In this way, during the turning phase, it has been possible to respect the tight tolerances imposed on linear displacement and parallelism between the planes of contact of main ball bearing, motor, encoder, and interface flange for instrumentation to be mouted on the derotators.
This last item has been the reference plane for the final machining of the mounting surfaces, for guides, motor and brake assemblies, otical mounting and CCD cameras. Optical tests on the final assembly confirmed the ground alignment on each derotator. Resolution and repetibility are also in keeping with the specification.
Some small modifications have been made to guarantee the request performances. The objective assembly is now adjustable on three degrees of freedom (rotation around three axis) instead of one. A special cover has been added on the CCD cameras to allow a forced ventilation for heat removal from Peltier hot face. On this way CCD operating temperature has been reduced to -35 C.
Special cages have been contructed to fix the electronic boxes on the structure.
