Research

In his research Álvaro will explore and develop a set of computationally feasible approaches to simulate and interpret experimental observations of laser-Induced electron diffraction (LIED) of complex molecules and molecular aggregates. His research project is algorithmically and computationally oriented and resides at the intersection of molecular physics, mathematics and data science.

Timepix3: single-pixel multi-hit energy-measurement behaviour

13 November 2024

The event-driven hybrid-pixel detector readout chip, Timepix3, has the ability to simultaneously measure the time of an event on the nanosecond timescale and the energy deposited in the sensor. However, the behaviour of the system when two events are recorded in quick succession of each other on the same pixel was not studied in detail previously. We present experimental measurements, circuit simulations, and an empirical model for the impact of a preceding event on this energy measurements, which can result in a loss as high as 70%. Accounting for this effect enables more precise compensation, particularly for phenomena like timewalk. This results in significant improvements in time resolution — in the best case, multiple tens of nanoseconds — when two events happen in rapid succession.

Keynote lecture at Sino-German Physics Conference

20 October 2024

Jochen presented a keynote lecture on CMI research at the 33rd Annual Meeting of the Chinese Society of Physicists in Germany (GCPD) in Jinan, Shadong, China. The lecture was well attained locally and, according to the organizers, followed by more than 10,000 people in the koushare online stream.
