One potential candidate for an online beam monitor is the LHCb Vertex Locator (VELO). This detector, originally developed for the LHCb experiment, has been adapted to the specific conditions of the clinical environment in a proton therapy centre. The semicircular design and position of its sensitive silicon detector offers a non-invasive way to measure the beam intensity without interfering with the beam core. In this contribution, modifications for VELO are described. The detector is synchronized with the readout of a locally-constructed Faraday Cup and the 25.7 MHz RF frequency of the cyclotron at the Clatterbridge Cancer Centre (CCC). Geant4 Monte Carlo simulations investigate the integration of the detector in the treatment line and behaviour of the beam during delivery. The capability of VELO as a beam monitor will be assessed by measuring the beam current and by monitoring the beam profile along the beamline this summer.
