3. Development of JAVA version of measurement
..in order to be independent of ROOT and Operating System.. Patryk Marsinkowski (student from Warsaw Technical University) summer internship Helped by Rafal Sarnecki (masters student from WTU) \ engineering thesis on the development of Java application Implement ALICE geometry Convert data sets (root files -> txt files) Create user interface Histograming package / saving of results Just received first version of whole package

8. Masterclass as part of Swedish Teachers programme at CERN
Mini-masterclass as part of the Swedish Teachers programme
at CERN (Training Centre, 1st November 2013)
28 persons (21 teachers and 7 High School students)
Very interested to bring it to their schools

9. Plans for Teachers Day in Greece
Plan Teachers’ Day in Thessaloniki (Greece) in February 2014 in a high school
Organised in collaboration with EKFE (Centre for Laboratory Equipment for Natural Sciences)
Aim
Make the MasterClasses known
Testbench for organizing local masterclasses in schools in the future

10. Virtual Machine for Windows
At the moment “Looking for strange particles in ALICE” is only available for Linux, Ubundu, MacOSX In view of Teachers Day in Greece an ubuntu virtual machine containing this measurement was developed (Dimitris Tsakonas, teacher of informatics) Tested remotely (using TeamViewer) Downloaded the whole Virtual Machine After testing we can make it available for 2014 masterclasses

11. Current Status Measurement basically the same as in 2013
Some cleaning of code – some new macros
Translations being added
Greek (being prepared)
Polish (being prepared)
Swedish (has been proposed)

12. Students (each group): Visual analysis of 15/30 events
First Part
Students (each group): Visual analysis of 15/30 events
tables + invariant mass histograms
Institute (all groups): Add up numbers / merge histograms / comments
Second Part
Students (each group): Analyse events in a centrality bin - invariant mass histograms
Students (each group): Fit curve/ subtract background-> find number of Λ, anti-Λ and K0s
Institute (all groups): Calculate yields of each particle type
(give initial number of events from which each sample has been extracted;
give global efficiency)
Calculate strangeness enhancement (ratio of yields normalised to Npart)
Strangeness enhancement plots -> To be presented by Institutes for video-conference
