====== Description ======
The K-cell evaporator is equipped with a Riber cell with a PBN crucible.
The maximum temperature is 1350 C. The system is pumped with a turbo pump and
can achieve a pressure in the 1e-8 mbar range after bake out (5e-7 without
baking and 1 day of pumping).
The system has a programmable Eurotherm temperature regulator and a manually
operated shutter.
====== Manual ======
==== Venting the chamber ====
- Switch off the ion gauge
- Switch off the turbo pump and rotary pump
- Vent //slowly// with the green valve on the turbo
==== Mounting the substrate ====
- Release the KF clamp and remove the sample holder
- Mount the sample using the spring
- Mount the sample holder and tighten the KF clamp
==== Pump down ====
- Switch on the rotary pump
- Wait 5 min, you can hear from the sound of the rotary pump when the final pressure is reached ( there is no pirani to measure intermediate pressure)
- Switch on the turbo pump
- When the turbo pump is at full speed (all the green LED's are on) the ion gauge can be switched on by pushing emission
- Pump until the desired pressure is reached (but always <1e-6 mbar)
==== Evaporating a film ====
- Program the Eurotherm with the Eurotherm control program (let the K-cell degas above the deposition temperature)
- Open the shutter and time the deposition
- Close the shutter
==== End ====
- Let the Eurotherm control program cool down the K-cell
- **Let the K-cell cool down completely to RT before removing the sample**
