Blok 1 - 2012

Neutronspredning kurset handler om neutroner, og koncentrerer meget af arbejdet om simulationer i simulerings-pakken McStas.

Neutronspredning studenterhjælp

Dette er anden gang jeg hjælper til i kurset, men første gang jeg er egenlig underviser (i stedet for bare hjælp til diverse opgaver). Sidste år var jeg med til at udvikle en Moodle side til undervisning (primært at stille opgaver i) og en videreudvikling af kursets notesæt (skrevet i LaTeX af Kim Lefmann) til et wiki-format ved brug af mediawiki wiki-formatet.

En oversigt over hvad der blev lavet i kurset kan ses i tabellen nedenfor:
