			=VNC viewer=
			*For Operators to use the camera via vnc to tune to the viewscreen, they need a device with 'real vnc' viewer installed. This runs on anything, even on an android phone.
			*To connect, use the IP address: 142.90.121.216. User name is 'pi'. Password is the same as to ssh into the raspberry pi. Ask Annika or Martin for the password.

			*The camera is mounted on a plastic holder at the bottom flange outside the beam path and tilted towards the phosphor screen to facilitate beam tuning. Next to the camera is an LED, which can be turned on to view the inside of the chamber and check detector/phosphor screen position and adjust the camera settings. '''Make sure to unbias the detector before turning on the LED!'''
			*The camera is controlled via a raspberry pi

			*The raspberry pi is running raspberry pi OS (previously Raspbian) and is based on debian linux
			*To connect to the pi remotely (provided it is registered on the network and connected to the ethernet), open a shell and ssh into it:
	<code>ssh -Y pi@anasen01.triumf.ca</code>		<code>ssh -Y pi@anasen01.triumf.ca</code>
			*Or login directly when monitor, mouse and keyboard are attached to the pi
	*Ask Annika or Martin for password		*Ask Annika or Martin for password

	*The little ribbon cables are a little tricky. They have to be inserted in a particular orientation. The best way to see is just to look at where the metal pins are on the cable and line that up to the contacts.		*The little ribbon cables are a little tricky.
