The 8th International Conference on Micro Pattern Gaseous Detectors (MPGD24)

Prototypes capable of detecting UV photons using photocathode vapors and their characterization data are well-documented in the literature. However, no research has been found that explores the impact of different vaporization methods of these gas-phase photocathodes on their quantum efficiency and signal production capabilities. In this study, Ethylferrocene (EF) and TMAE photocathode vapors were vaporized using heating and ultrasonic vibration methods, and the photon interaction performance of the resulting vapors was compared. Additionally, mixtures of these vapors in various ratios were tested, and the results were analyzed and compared. The findings from these experiments will be presented.
