粒子加速器环形截面图

一幅等轴测工程图风格的环形粒子加速器截面插图。剖面从外到内依次显示：混凝土防护层（灰色剖面线方块）、超导二极磁铁壳体（拉丝银色圆柱）、铌钛线圈绕组（浅蓝色线圈）、束流管（不锈钢细管）——中心两束反向质子束以品红与青色发光线表示。右侧标注箭头：「Concrete shield: 3 m」、「Magnet bore: 56 mm」。左上角颜色图例。背景为深海蓝方格纸，等轴测 30° 网格线隐约可见。顶部等宽字体标题栏：「粒子加速器环形截面图」。整体配色冷峻技术感：银、板岩、青、品红。

An isometric technical cross-section illustration of a circular particle accelerator ring segment, styled as an engineering schematic. The cutaway reveals concentric layers: outermost concrete shielding (hatched grey blocks), superconducting dipole magnet housing (brushed silver cylinder), niobium-titanium coil windings (pale blue coils), beam pipe (thin stainless-steel tube) at the center with two counter-rotating proton beams shown as glowing magenta and cyan lines. Dimension callout arrows on the right side label "Concrete shield: 3 m", "Magnet bore: 56 mm". Color-coded legend in upper-left corner. Isometric 30° grid lines faintly visible. Background is dark navy graph paper. Title bar at top in monospace font: "Dipole Magnet Cross-Section — LHC-type" — note: no real brand, generic description. Cold, technical color palette: silver, slate, cyan, magenta.
