5. Scientific Program During the selection process, we had solicited opinions from members of the Scientific Program Committee regarding many issues such as the selection of parallel session conveners, plenary session talks, and time allocation to the sessions and the plenary talks. In general, there had been very good input, but in many cases replies came too slow. Topics for plenary sessions had been selected on the basis of the most recent developments in the field with some considerations given to regional balance. The responsibilities for selecting topics for parallel sessions had been largely given to the session conveners who had full authority in organizing topics in his/her session. Details are as below:

c. Posters We had organized both lab and individual posters. The following 19 labs joined the lab poster session: ANL BNL CCLRC CERN DAPNIA DESY FNAL IHEP KAMIOKANDE KEK KLOE LAL LBNL LEPP LNGS NOVERSBIRSK PLS SLAC TRIUMF We solicited through session conveners, but only a few individuals participated.

6. Finance a. Income The registration fee was a little less than 200,000 USD. The financial support from various sources was about 45,000 USD. IUPAP 14,500 USD CAS 10,000 USD NSFC 20,000 USD CPS 1,200 USD Total income: 245,700 USD

6. Finance b. Outlay Conference rooms 6,000 / day x 3 days = 18,000 USD 8,000/day x 3 days = 24,000USD Proceedings 38 x 900 copies = 34,200 USD Reception 25 x 900 persons = 22,500 USD Banquet 45 x 1,000 persons = 45,000 USD Tea breaks 2.5 x 900 x 12 = 27,000 USD Conference bag 14$ x 1000 = 14,000$ Transportation 11,000$

6. Finance Office Equipments (mainly for computers and the registration room) 15,000 USD Support to students and participants from developing countries 35,000 USD (China Pakistan Russia Argentina Czech Vietnam Ukraine Serbia and Montenegro India Korea Russia) Meeting support 5,000USD (Including two C-11 meetings, ICFA, ILCSC one day, Interactions Collaboration two full days) Total outlay: 250,700 USD In addition to pay the deficit of 5000 USD, IHEP also supported a large amount of manpower, postages, office supply in total about 12,000 USD.

6. Finance The conference should have more income, and the relatively larger expenditure was mainly due to 1) Number of people showing up was much less than expected, and yet most contracts had been signed on the basis of 900 or 1000 people, proceedings and the banquet for instance, 2) We had supported too many local students and participants from poor local institutions.

7. Proceedings Proceedings (two volumes) were contracted to WSP, Singapore and are now ready and are being distributed.

8. Summary The conference had been very successful in that it had been carried out in full conformity with the IUPAP values and principles, through the conference scientific ideas had been exchanged among the participants, friendship and cooperation had been strengthened. Hereby I would like to be on behalf of the host institution to express my thanks to all the sponsors and everybody here who made it available for us to host ICHEP’04.
