Hitachi 7800 specific installation¶

Install myami package on the associated camera computer¶

• Instead of installing myami package on HHT scope-controlling PC, the access can be through the computer controlling the digital camera.

• No special supporting package needed.

h2.hht.cfg

hht.cfg records some instrument specific parameters that are required to convert the instrument output to SI units that Leginon depends on.

The values in pyscope/jeol.cfg.template is based on NYSBC HT7800 equipped with TVIPS XF416. You may start with these and copy it
to pyscope/hht.cfg or other valid myami configuration file locations.

instruments.cfg¶

[scope]
class: hitachi.HT7800
cs: 3e-3

• Cs for HR and HC modes are 3.0 mm and 5.2 mm, respectively. You will most likely use HR mode on the final image.

• You will also be adding the camera in the same instruments.cfg since this file is located on the camera computer in this instruction.

Testing with pyscope¶

In python command

from pyscope import hitachi
t =hitachi.HT7800()
t.getHighTension()

You should get the current gun high tension value in Volts.
