-=====JSPM-4500A UHV AFM======
-MCh's AFM/STM-system is a JSPM-4500A "Ultrahigh Vacuum Atomic Force Microscope" made by JEOL. It consists out of three chambers: exchange, sample cleaning and observation chamber.
-====Technical Specifications====

-^ Vacuum | Exchange chamber | 1*10-5 Pa |
-^  | Sample cleaning | 5*10-7 Pa (down to 10-7 Pa) |
-^  | Observation chamber | < 3*10-8 Pa |
-^ Pumping system | Exchange chamber | oil rotary pump + turbo molecular pump |
-^ | Treatment chamber | sputter ion pump (SIP2) / Ti sublimation pump (TSP) |
-^ | Observation chamber | sputter ion pump (SIP1) / Ti sublimation pump (TSP) |
-^ Vacuum gauges  | Exchange chamber | Pirani/Penning gauge |
-^ | Treatment chamber | Pirani/Penning gauge |
-^ | Observation chamber | nude filament (ion) gauge |
-^ Detection signal ^ JSPM-4500 |
-^ AFM contact mode | 10 pN up to 10nN |
-^ Tunnelling current (STM mode) | 50 pA up to 1µA |
-Currently, the AFM/STM has not been used for a while. An AFM/STM-training is considered for some MCh staff.
