22. TLS Contributions to NAHUAL Person Power: Expertise in absorption cell Small workshop that is overstretched → small parts CAD work possible Limited Electronics/Computer support Science contributions

23. TLS Contributions to NAHUAL Money: Best to spread costs over several budget years 80.000 – 100.000 in 2007 Budget 2008/2009 Budget will be prepared early next year Money has to be spent in a given budget year. Transfer to next year possible but difficult Specific items need to be identified and bids made Memorandum of Understanding important
