There are various applications available for remote (video) communication. Nikhef advices using the Zoom tool. This tool can be used under Windows, Mac OSX and various Unix distributions and is user-friendly. The free version of Zoom offers meetings for up to 40 minutes. At the moment (17-3-2020) Nikhef has purchased 20 Pro licenses which meetings can be organized up to 24 hours. Getting a Pro license requires an administrative action from the helpdesk. If you need this, send an email to helpdesk-at-nikhef.nl and we will look into it.

Windows installation and instructions

For Windows, as the organizer of a meeting, follow the steps below.

  • Click Resources at the top right and choose Download Zoom Client.


  • Click Download and install it afterwards. Installation is simple and requires no interaction.


  • After installation, the Zoom software opens automatically and a login screen appears. Participants of a meeting can participate with the link and the associated PIN code that the organizer shares, then the Zoom software that is needed is installed on the computer.


  • If you want to start a meeting. Choose "Sign in". This requires a (free) Zoom account. This can be created by clicking on "Sign up Free" in the login screen. Use your Nikhef email address for this. Hosting a meeting that takes longer then 40 minutes requires a license, 20 licenses are available.

  • After logging in you can start a new meeting by clicking on "New meeting".

Meeting options

It is possible to create (recurring) meetings that can start without the organizer being present. That is useful for "coffee meeting rooms". Everybody can dial in without the host (organizer) being present.

Recipe for (recurring) meetings without the organizer

  • Create a meeting. For a permanent room, let it start at 12AM and choose a duration of 24 hours.
  • Optionally choose for a recurring meeting. All meetings will have the same meeting-ID.
  • Enable join before host (under Advanced Options)
  • Disable waiting room
  • Disable authentication requirement

The organizer (host) of the meeting should start the meeting! If that is not possible, an alternative host can be appointed. The alternative host must be another licensed user.


Other Tips

  • When many participants are expected, choose Mute participants on entry (under Advanced Options) to avoid a cacophony on start of the meeting. Participants can unmute when they want to speak.
  • Use a password for the meeting to keep uninvited participants away. Consider how you distribute the password to the participants - putting it on a publicly accessible web page (or Indico agenda page) defeats the purpose of a password.
