On 1 December at 16:00 in A101 aud. (National Center for Physical and Technological Sciences, Saulėtekio ave. 3), Dr Jascha Peter Grabowsky will give a public lecture "Guiding Beams and Twisting Spins: The Precision Channeling Studies of TWOCRYST and ALADDIN". He is a particle physicist and a long-standing member of the LHCb experiment.
Abstract
When charged high-energy particles pass through a bent crystal lattice, the interplanar potential acts like an intense magnetic field, steering both their paths and their spins. The TWOCRYST experiment at CERN uses high-quality, precisely characterized crystals to study this channeling effect at unprecedented energies. It serves as a proof of principle for the planned ALADDIN experiment, which will measure the spin precession of charmed baryons. Observing this subtle effect will, for the first time, enable direct exploration of their magnetic and electric dipole moments. This talk will show how advanced materials engineering and crystal metrology open new avenues for probing fundamental particle properties—turning bent crystals into precision instruments for modern physics.
