Advanced Oncotherapy
18th May 2020
Geneva, Switzerland
Job Type


Advanced Oncotherapy is an innovative technology business focused on delivering a proton-based
radiotherapy system using technology originally developed and tested at the world- renowned CERN
facility in Switzerland.
Proton beam therapy is likely to play a crucial role in the affordable treatment of cancer in the future.
Advanced Oncotherapy’s system is based on a linear accelerator (‘LIGHT’) technology that is superior
to traditional cyclotron/synchrotron accelerators and significantly less expensive to implement than its
competitors. The company acquired the technology through the acquisition of A.D.A.M. SA, a CERN
spin-off company, in 2013.
The first LIGHT systems is being installed and commissioned at our test site at STFC Daresbury, in
the north of England, prior to shipping to our customer sites.
The post holder will be in charge of the installation and commissioning of the radiofrequency
equipment, radiofrequency power sources, power supplies, power converters foreseen in the LIGHT
proton therapy accelerator at Daresbury STFC (UK). As a beam RF and power expert, he/she will
have to coordinate or participate in all the needed tests to operationalise the equipment. The post
holder will have an active role during the beam commissioning in the control room, by performing
measurements, developing analysis tools and debugging the accelerator. Once commissioning is
over, he/she will be involved in the continuous operation and maintenance of the machine in the
control room. The role might involve travel in Europe and work on shifts.

Key Responsibilities
Area 1: Support the radiofrequency (RF) and electrical power areas at Daresbury:
• Be part of the team who performs the low and RF power acceptance tests of the
accelerating structures.
• Support the RF conditioning of the accelerating structures.
• RF characterization and acceptance of RF network components, readout and preamplification stages calibrations from low level RF to high power RF source output and
RF measurements from the low-level RF generation to the high-power RF source
• Support the RF interventions on the RF systems (accelerator cavities, pickups, readout
chain, pre-amplification chain, low level RF).
• Support the activities on the installation and setting up of the high RF power systems.
• Support in characterizing and carry out measurements campaigns for currents in
electromagnets and voltages in power systems.
• Troubleshoot technical problems of the accelerator related to RF and high-power
Area 2: Support during beam commissioning phases.
Area 3: Writing reports, documentation and first support contact of LIGHT operators for High Power
and RF related issues.
• BSc in Physics, Power Systems or Electronic Engineering;
• University studies with emphasis on EM theory and propagation;
• Knowledge of standard instrumentation for RF measurements such as Vector Network
Analyzer, Spectrum Analyzer, Oscilloscope, Signal Generators and/or able to learn it
• Measurements of high currents and high voltages;
• Knowledge of power converter systems and high-power amplifiers (IOTs and
