Very good course. I have taken the NPAS course in Lund in 2015 and used this course as a refresher. The instructors are very good and experts on their respective fields. One does not require advanced bed knowledge on Physics or Engineering to follow the course. A must for everyone working around particle accelerators but don't necessarily work with particle accelerator physics.

I only have basic accelerator background and the course have helped me improve my understanding of accelerator technology

Very interesting course !

Short videos with clear explanations and good pictures/illustrations

Description of complex devices in particle accelerator field are explained in very lucid way.

This course is really good and interesting to about particle accelerator.

Great instructors and content

Excellent, thank you.

I am a vacuum scientist at a light source and I used this course to fill gaps in my knowledge. For instance, the RF and magnet sections were very helpful because I do not interact with these systems often and I have not had to learn much about them thus far.

However, I noticed some gaps between quiz questions and the videos and there were small inaccuracies in the information given. For instance, the vacuum instructor called a Pirani gauge a cold cathode gauge after discussing Pirani gauges under the umbrella of thermal gauges. To give another example, the question pertaining to beam coordinates gave five parameters rather than the needed si (probably just a typographic error). I did not find any gaps or inconsistencies stifling but someone with less experience in the field might.

Is there any possibility of more advanced in-depth modules? It would be very nice to have, say, five weeks on RF systems.

The content is instructive. I recommend this course for all users of accelerators who want to know the basics of the facilities they are using. If we can have improvements in a few points, it would be better even more.

Typos: There are a lot of typos in the subtitles and quizzes.

Additional explanations: Week 4 would be better if it contains reading materials on the additional details.

The course was very interesting and engaging. Some of the parts were like just exhibits of accelerator components, more explanation could be added. Such courses are really difficult to find. Thanks to the instructors and team.

Excellent course, thank you so much. I am about to start a thesis at former IPNO in Orsay, and sure those knowledge will be of use.

Some of the English could be clearer, but the information and delivery is generally great!

Interesting course to understand the way particle accelerators work.

I do not recommend this course if you're intending to learn any deep concepts.

1) The course instructors look like they don't want to be there, and are basically present to read from a script. The slides are next to useless because they barely help illustrate anything the instructors say. Week 4 on vacuum technologies is the worst: I could barely make out many important terms. Even the transcripts describe many words/phrases as "unintelligible" and no one from the course team has decided to fix the transcripts to at least help with how incomprehensible things already are.

2) Much of the content is shallow, so you learn a bunch of names/terms but there is no attempt to help you understand concepts or principles. Most of the videos have no link to one another, and they don't even try and show you how the things they mention fit in together on a whole. A very simple thing to do would have been to provide a summary with a quick comparison at the end of each section of all the objects/technology that have been touched upon.

3) Answering quiz questions will involve a bunch of guess work because videos are mainly terrible at describing and explaining.
