In this work, we develop a first-order, three-dimensional, forward model of the ejecta plume behavior resulting from this cratering event, and then adjust the model parameters to match the flyby-spacecraft observations of the actual ejecta plume, image by image. This modeling exercise indicates Deep Impact to have been a reasonably “well-behaved” oblique impact, in which the impactor–spacecraft apparently struck a small, westward-facing slope of roughly 1/3–1/2 the size of the final crater produced (determined from initial ejecta plume geometry), and possessing an effective strength of not more than Y¯ = 1–10 kPa. The resulting ejecta plume followed well-established scaling relationships for cratering in a medium-to-high porosity target, consistent with a transient crater of not more than 85–140 m diameter, formed in not more than 250–550 s, for the case of Y¯ = 0 Pa (gravity-dominated cratering); and not less than 22–26 m diameter, formed in not less than 1–3 s, for the case of Y¯ = 10 kPa (strength-dominated cratering).

Yoshioka, KEK, Oho, Tsukuba, Ibaraki 305-0801, Japan, T. Browder, Univ. of Hawaii, 2505 Correa Road, Honolulu, HI 96822, U.S.A. Abstract The commissioning of the KEKB B–Factory storage rings started on Dec. 1, 1998. The two rings both achieved a stored current of over 0.5 A after operating for four months. The two beams were successfully collided several times. The commissioning stopped on Apr. 19, taking a 5-week break to install the Belle detector. 1 BRIEF HISTORY OF THE COMMISSIONING The KEKB B–Factory[1] consists of two storage rings, the LER (3.5 GeV, e+) and the HER (8 GeV, e−), and the in- jector Linac/beam-transport (BT) system. The Linac was upgraded from the injector for TRISTAN, and was com- missioned starting in June 1997, including part of the BT line. The injector complex was ready before the start of commissioning of the rings.[2] Figure 1 shows the growth of the stored currents in the two rings through the period of commissioning.

    OCTOBER 2 0 0 6 �������������� http://www.universetoday.com �������������� TAMMY PLOTNER WITH JEFF BARBOUR 283 SUNDAY, OCTOBER 1 In 1897, the world’s largest refractor (40”) debuted at the University of Chica- go’s Yerkes Observatory. Also today in 1958, NASA was established by an act of Congress. More? In 1962, the 300-foot radio telescope of the National Ra- dio Astronomy Observatory (NRAO) went live at Green Bank, West Virginia. It held place as the world’s second largest radio scope until it collapsed in 1988. Tonight let’s visit with an old lunar favorite. Easily seen in binoculars, the hexagonal walled plain of Albategnius ap- pears near the terminator about one-third the way north of the south limb. Look north of Albategnius for even larger and more ancient Hipparchus giving an almost “figure 8” view in binoculars. Between Hipparchus and Albategnius to the east are mid-sized craters Halley and Hind. Note the curious ALBATEGNIUS AND HIPPARCHUS ON THE relationship between impact crater Klein on Albategnius’ southwestern wall and TERMINATOR CREDIT: ROGER WARNER that of crater Horrocks on the northeastern wall of Hipparchus. Now let’s power up and “crater hop”... Just northwest of Hipparchus’ wall are the beginnings of the Sinus Medii area. Look for the deep imprint of Seeliger - named for a Dutch astronomer. Due north of Hipparchus is Rhaeticus, and here’s where things really get interesting. If the terminator has progressed far enough, you might spot tiny Blagg and Bruce to its west, the rough location of the Surveyor 4 and Surveyor 6 landing area.

  • View Responses of Scouts, Scout Leaders, and Scientists Who Were Scouts
    ABSTRACT This study of science education in the Boy Scouts of America focused on males with Boy Scout experience. The mixed-methods study topics included: merit badge standards compared with National Science Education Standards, Scout responses to open-ended survey questions, the learning styles of Scouts, a quantitative assessment of science content knowledge acquisition using the Geology merit badge, and a qualitative analysis of interview responses of Scouts, Scout leaders, and scientists who were Scouts. The merit badge requirements of the 121 current merit badges were mapped onto the National Science Education Standards: 103 badges (85.12%) had at least one requirement meeting the National Science Education Standards. In 2007, Scouts earned 1,628,500 merit badges with at least one science requirement, including 72,279 Environmental Science merit badges. ―Camping‖ was the ―favorite thing about Scouts‖ for 54.4% of the boys who completed the survey. When combined with other outdoor activities, what 72.5% of the boys liked best about Boy Scouts involved outdoor activity. The learning styles of Scouts tend to include tactile and/or visual elements. Scouts were more global and integrated than analytical in their thinking patterns; they also had a significant intake element in their learning style. ii Earning a Geology merit badge at any location resulted in a significant gain of content knowledge; the combined treatment groups for all location types had a 9.13% gain in content knowledge. The amount of content knowledge acquired through the merit badge program varied with location; boys earning the Geology merit badge at summer camp or working as a troop with a merit badge counselor tended to acquire more geology content knowledge than boys earning the merit badge at a one-day event.

  • Status of Super-Kekb and Belle Ii∗
    Vol. 41 (2010) ACTA PHYSICA POLONICA B No 12 STATUS OF SUPER-KEKB AND BELLE II∗ Henryk Pałka The H. Niewodniczański Institute of Nuclear Physics Polish Academy of Sciences Radzikowskiego 152, 31-342 Kraków, Poland (Received November 29, 2010) The status of preparations to Belle II experiment at the SuperKEKB collider is reviewed in this article. PACS numbers: 11.30.Er, 12.15.Hh, 13.20.He, 29.20.db 1. Introduction The Belle detector [1] has stopped data taking in June 2010. A decade- long operation of the experiment at the asymmetric beam energy electron- positron collider KEKB [2] resulted in a data sample of an integrated lumi- nosity exceeding 1 ab−1. This would not be possible without the excellent performance of the KEKB. The collider has reached the world record in- stantaneous luminosity of 2:2 × 1034 cm−2s−1 (Fig. 1), more than twice the design luminosity. Several technological innovations contributed to this achievement, among them crab cavities developed at KEK and successful implementation of continuous injection. Fig. 1. Time-line of KEKB peak luminosity. ∗ Lecture presented at the L Cracow School of Theoretical Physics “Particle Physics at the Dawn of the LHC”, Zakopane, Poland, June 9–19, 2010. (2595) 2596 H. Pałka By the precise measurement of the CKM angle φ1 by Belle and BaBar, its companion B-meson factory experiment at SLAC [3], the Kobayashi– Maskawa mechanism of CP violation [4] has been confirmed. Following the experimental confirmation M. Kobayashi and T. Maskawa were awarded the 2008 Nobel Prize in Physics. Numerous other physics results of B-meson factory experiments further support the hypothesis that the matrix of three- generation quark mixing is the dominant source of CP violation in B- and K-meson decays.

KEKB accelerators were installed in the same tunnel where the TRISTAN accelerator was. There were some constraints due to the reused equipment. The control system is based on Experimental Physics and Industrial Control System (EPICS). In order to reduce the cost and labor for constructing the KEKB control system, as many CAMAC modules as possible are used again. The guiding principles of the KEKB control computer system are as follows: use EPICS as the controls environment, provide a two-language system for developing application programs, use VMEbus as frontend computers as a consequence of EPICS, use standard buses, such as CAMAC, GPIB, VXIbus, ARCNET, RS-232 as field buses and use ergonomic equipment for operators and scientists. On the software side, interpretive Python and SAD languages are used for coding application programs. The purpose of the radiation safety system is to protect personnel from radiation hazards. It consists of an access control system and a beam interlock system. The access control system protects people from strong radiation inside the accelerator tunnel due to an intense beam, by controlling access to the beamline area.
