IMALION – which stands for IMplantation of ALuminum IONs – is a facility originally designed for applications in photovoltaics and other branches in semiconductor industry. The idea was to create and guide a milliampere beam of low charged metal ions so that targets with a width of 20 cm and more can be irradiated homogeneously with minimal differences in intensity and entrance angle of the incoming beam over the entire surface. In this poster, we outline the solutions which had to be found during the realization of the project. This concerns the production of a milliampere metal ion current in a newly designed electron cyclotron resonance (ECR) ion source combined with an internal sputter magnetron device. Stable operation of the sputter magnetron under ECR magnetic mirror conditions has been proven by optical spectroscopy and Langmuir probe measurements. Furthermore, electrostatic and magnetic beamline elements developed for precision guiding of a low energy but high intensity beam as well as high intensity ion beam diagnostics are presented and ion beam transportation simulations are shown.

A CW-compatible, pulsed H⁻ superconducting RF linac (a.k.a. PIP-II) is envisaged as a possible path for upgrading Fermilab’s injection complex [1]. To validate the concept of the front-end of such machine, a test accelerator (a.k.a. PXIE) [2] is under construction. The warm part of this accelerator comprises a 10 mA DC, 30 keV H⁻ ion source, a 2m-long LEBT, a 2.1 MeV CW RFQ, and a MEBT that feeds the first cryomodule. In addition to operating in the nominal CW mode, the LEBT should be able to produce a pulsed beam for both PXIE commissioning and modelling of the front-end nominal operation in the pulsed mode. Concurrently, it needs to provide effective means of inhibiting beam as part of the overall machine protection system. A peculiar feature of the present LEBT design is the capability of using the ~1m-long section immediately preceding the RFQ in two regimes of beam transport dynamics: neutralized and space charge dominated. This paper introduces the PXIE LEBT, reports on the status of the ion source and LEBT installation, and presents the first beam measurements.
