									BAKE UNIT                                                        TITANIUM SUBLIMATION PUMP
BU-3-230-32A                                                     CONTROL UNIT, CU -TI -R2
T he bake unit BU-3-230-32A is used to control the               CreaTec has developed a power supply to control a
baking of vacuum systems. It contains:                           typical titanium sublimation pump through the
                                                                 control computer. The power supply contains:
- power supplies for the different heating stages
  of the bakeout system                                          - two independent circuits for titanium sublimation
- a Eurotherm controller to control the bakeout                    pumps
  temperature via a type-K thermocouple                          - selected thyrotakt controllers and transformers
- a timer to control the bakeout time                              adapted to the titanium filaments
                                                                 - power indicators on the front panel




The computer control of the bake unit is realized
either by switching it on or off using a relay or by             - manual power adjustment on the front panel
supplying a 5 Volt TTL logic signal.                             - a computer interface by 5 Volt TTL logic signal

                                                                 Using a multitasking control system like EMERALT
                                                                 (see page 10), the titanium sublimation pump of the
                                                                 MBE system can be driven economically with
                                                                 CU-TI-R2.
