A photocathode is a thin multilayer, usually deposited onto a transparent glass window. Its function is to absorb soft (visual) photons entering through the window, and to subsequently emit a detectable photoelectron into the adjacent vacuum. The probability that an incoming soft photon results in the emission of a photoelectron never exceeded 40%. With this high risk/high impact...
We propose an opto-mechanical accelerometer working at the precision-limits imposed by quantum mechanics. Our chip-based approach combines our state-of-the-art designs in both nanophotonics and quantum phononics to pioneer new types of telecom sensors which are quickly becoming widespread in modern society. Using techniques recently developed at TU Delft we are now able to manipulate highstress films with unique optical...
Proton therapy is a promising cancer treatment modality with the ability to concentrate the deposited dose (Bragg peak) on the tumour while minimising collateral damage due to low dose to healthy surrounding tissue. However, uncertainties in the Bragg peak position limit clinical utility. Especially due to range uncertainties, patient movement and tissue deformation, the localisation accuracy is...
