A COMPARATIVE STUDY BETWEEN SIMULATED AND MEASURED BEAM'S QUALITY OF 30 MeV CYCLOTRON AT KFSHRC

Abstract At King Faisal Specialist Hospital and Research Centre (KFSHRC), the C-30 Cyclotron (manufactured by IBA) is used to produce radioisotopes for medical purposes. Working with very expensive machine dedicated for patients needs full attention and understanding of how beam can be controlled safely inside beam transport system. Moreover, knowledge of influence of magnetic lenses on charged particles is desired. Therefore, using off-line source such as PC-based beam simulator allows an operator to immediately see the effect of various magnetic lenses attached to the beam line. Initially, the magnetic field of quadruples and steering magnet was recorded using Hall probe Teslameter. The magnetic field values then uploaded into the Beam simulator in which beam quality was recorded and analysed

Room-Temperature Inter-Dot Coherent Dynamics in Multilayer Quantum Dot Materials

The full blossoming of quantum technologies requires the availability of easy-to-prepare materials where quantum coherences can be effectively initiated, controlled, and exploited, preferably at ambient conditions. Solid-state multilayers of colloidally grown quantum dots (QDs) are highly promising for this task because of the possibility of assembling networks of electronically coupled QDs through the modulation of sizes, inter-dot linkers, and distances. To usefully probe coherence in these materials, the dynamical characterization of their collective quantum mechanically coupled states is needed. Here, we explore by two-dimensional electronic spectroscopy the coherent dynamics of solid-state multilayers of electronically coupled colloidally grown CdSe QDs and complement it by detailed computations. The time evolution of a coherent superposition of states delocalized over more than one QD was captured at ambient conditions. We thus provide important evidence for inter-dot coherences in such solid-state materials, opening up new avenues for the effective application of these materials in quantum technologies
