Running a Profile

Before you can run a profile, ensure you have:

Completed the installation as described on page 10.

Switched on the instrument (see section 17).

Loaded a sputter/coating target or loaded an evaporation source (see page 54).

To run a profile:

1.

Load your sample onto the center of the sample stage.

2.

Close the top cover assembly and press it firmly down to secure the latch.

3.

Tap  on  the  down  arrow  button  to  open  the  dropdown  list  of  profiles  (see 

Figure 

3-2

). 

Figure 3-2.

Selecting a profile

4.

The  Q150T  has several  default  profiles  for  common  tasks  as  shown  in  Table  1. 
Tap on the name of the profile you want to run.

QT Pulse cord evap

Evaporation using carbon cord (see page 32)

QT Controlled pulse

Evaporation using FTM termination of carbon cord (see page 32)

QT Vent chamber

Vent sample chamber

QT Vacuum shutdown

Pumps chamber to 1mBar to allow shutdown under vacuum

* Profile only present on systems equipped with FTM.

5.

Tap  on  the 

Run  Profile

button. The Q150T starts pumping the sample chamber. 

The progress of the run is shown through a series of on-screen messages (Figure 
3-3).
