LATA @LNL

LATA (LAboratorio per Tecnologie di Acceleratori) @ LNL

Introduction

INFN-LNL conducts since a couple of decades state-of-the-art activity in the development of both superconducting and normal conducting accelerators.  While the former led to the realization of a number of laboratories for cavity production and tests (chemical laboratory, sputtering laboratory, two cryogenic labs for SC cavity tests, RF lab), no dedicated lab has been so far setup for normal conducting accelerating structures and their related accelerator elements.  Special lab specs are hence required and will be built for experimental activities on high current proton or ion linacs.

Activity on these structure span in LNL from:

  • the TRASCO (TRAsmutazione di SCOrie, i.e. waste trasnmutation) linac, featuring the high current ion source TRIPS (built at LNS and improved at LNL), a 100% duty cycle RFQ and research and development activities on high power beam targets;
  • to the IFMIF RFQ and its high power couplers, tuning system, alignment system, etc.; the IFMIF-RFQ has been fully assembled and preliminarily tested at INFN-LNL, in collaboration with INFN departments in Padova, Torino and Bologna, and then transported to Rokkasho (Japan) for its exploitation;
  • to the Drift Tube Linac (DTL) for the European Spallation Source, being built by INFN-LNL in collaboration with a galaxy of mostly rearby companies.

The planned infrastructure LATA.

For all these activities, in the reasonable assumption of their continuation in decades to come, a dedicated laboratory is envisaged and its construction planned for the period 2020-2022.  The lab, albeit able to host several kinds of accelerator components for required tests, if compliant with the building features, will be specialized for low and high power tests of normal conducting accelerator structures.

It will feature an available surface of around 1000 m2, an overall electrical power of 5 MVA and a consistent refrigeration capability.  It will be equipped with at least four separated areas for high power tests, properly shielded for radioprotection reasons, of 200 m2 each.

Available infrastructures will include RF amplifier system at 352 and 175 MHz at a total 1,2 MW, as well as circulator, power loads and all related high-P components, digital RF controllers, RF structure cooling skids,…

As a mere reference, similar RF structures and related infrastructures – used for TRASCO, IFMIF and ESS projects – are shown in fig. 1.  They are at present scattered in several smaller areas of the LNL premises, among which an experimental hall which will soon be devoted to experimental activities of the being built SPES facility.

Details on the new infrastructure will be updated on this web-page, as long as information will be known and the layout progressively outlined in its final form.
