Superconducting magnet system for a 28GHz ECR ion source has been *** maximum axial magnetic fields are 4t at the rf injection side and 2t at the beam extraction side,*** hexapole magnetic field is about 2t on the inner surface of the plasma *** superconducting coils consist of six solenoids and six racetrack windings for a hexapole *** kinds of coil arrangements were investigated:one is an arrangement in which the hexpole coil is located in the bore of the solenoids,and another is the reverse of *** coils use Nbti-Copper conductor and are bath-cooled in liquid *** six solenoids are excited with individual power supplies to search for the optimal axial field *** current leads use high tc material and the cryogenic system is operated in LHe re-condensation mode using small *** thermal insulated supports of the cold mass have also been designed based on the calculated results of the magnetic *** heat loads to 70K and LHe stages were estimated from the design of the supports,the current leads and so on.

At RIKEN,three ECR ion sources(10GHz ECRIS,18GHz ECRIS and liquid He-free SC-ECRIS) are operated as external ion sources of heavy ion *** the last year,multi-charged uranium ion beam was produced from 18GHz ECRIS by using UF_6 and the ^(238)U ion was successfully accelerated by the accelerator complex which consists of the RFQ linear accelerator,RIKEN heavy ion linear accelerator(RILAC)and RIKEN ring cyclotron accelerator(RRC).the typical beam intensity of^(238)U^(14+) was about 2pμA on faraday cup after analysing magnet.^(70)Zn beam was still supplied for the new super-heavy element search experiment with insertion *** beam of^(70)Zn^(16+) was produced for long term(～43 days)without vacuum break and remarkably low material consumption rate(～100μgr/h).We already supplied Zn beam longer than 200 days for this experiment.^(48)Ca ion was also produced by insertion method using^(48)CaO rod for the nuclear physics *** this contribution,we will present ion source parameter and techniques for production of each of the metal ions.

AIM:to determine the effect of oral sumatriptan on gastric emptying using a continuous 13 C breath test(BreathID system).MEtHODS:ten healthy male volunteers participated in this randomized,2-way crossover *** subjects fasted overnight and were randomly assigned to receive a test meal(200 kcal/200 mL) 30 min after pre-medication with sumatriptan 50 mg(sumatriptan condition),or the test meal alone(control condition).Gastric emptying was monitored for 4 h after administration of the test meal by the 13 C-acetic acid breath test performed continually using the BreathID ***,using Oridion Research Software(β version),the time taken for emptying of 50% of the labeled meal(t 1/2) similar to the scintigraphy lag time for 10% emptying of the labeled meal(t lag),the gastric emptying coefficient(GEC),and the regression-estimated constants(β and κ) were *** statistical significance of any differences in the parameters were analyzed using Wilcoxon's signed-rank ***:In the sumatriptan condition,significant differences compared with the control condition were found in t 1/2 [median 131.84 min(range,103.13-168.70) vs 120.27 min(89.61-138.25);P = 0.0016],t lag [median 80.085 min(59.23-125.89) vs 61.11 min(39.86-87.05);P = 0.0125],and β [median 2.3374(1.6407-3.8209) vs 2.0847(1.4755-2.9269);P = 0.0284].there were no significant differences in the GEC or κ between the 2 ***:this study showed that oral sumatriptan significantly delayed gastric emptying of a liquid meal.
